	A. Ledeul, A. Savulescu, G. Segura, B. Styczen CERN, Meyrin, Switzerland
	The CERN HSE - occupational Health & Safety and Environmental protection - Unit develops and operates REMUS - Radiation and Environmental Unified Supervision - , a Radiation and Environmental Supervision, Control and Data Acquisition system, covering CERN accelerators, experiments and their surrounding environment. REMUS is now making use of modern data streaming technologies in order to provide a secure, reliable, scalable and loosely coupled solution for streaming near real-time data in and out of the system. Integrating the open-source streaming platform Apache Kafka allows the system to stream near real-time data to Data Visualization Tools and Web Interfaces. It also permits full-duplex communication with external Control Systems and IIoT - Industrial Internet Of Things - devices, without compromising the security of the system and using a widely adopted technology. This paper describes the architecture of the system put in place, and the numerous applications it opens up for REMUS and Control Systems in general.

MOPHA011	Improving Gesture Recognition with Machine Learning: A Comparison of Traditional Machine Learning and Deep Learning	network, GUI, interface, controls	214
	R. Bacher DESY, Hamburg, Germany
	Meaningful gesturing is important for an intuitive human-machine communication. This paper deals with methods suitable for identifying different finger, hand and head movements using supervised machine learning algorithms. On the one hand it discusses an implementation based on the k-nearest neighbor classification algorithm (traditional machine learning approach). On the other hand it demonstrates the classification potential of a convolutional neural network (deep learning approach). Both methods are capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements. The details of the different methods with respect to recognition accuracy and performance will be presented.

MOPHA044	Development of Ethernet Based Real-Time Applications in Linux Using DPDK	Linux, network, feedback, Ethernet	297
	G. Gaio, G. Scalamera Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	In the last decade Ethernet has become the most popular way to interface hardware devices and instruments to the control system. Lower cost per connection, reuse of existing network infrastructures, very high data rates, good noise rejection over long cables and finally an easier maintainability of the software in the long term are the main reasons of its success. In addition, the need of low latency systems of the High Frequency Trading community has boosted the development of new strategies, such as CPU isolation, to run real-time applications in plain Linux with a determinism of the order of microseconds. DPDK (Data Plane Development Kit), an open source software solution mainly sponsored by Intel, addresses the request of high determinism over Ethernet by bypassing the network stack of Linux and providing a more friendly framework to develop tasks which are even able to saturate a 100 Gbit connection. Benchmarks regarding the real-time performance and preliminary results of employing DPDK in the acquisition of beam position monitors for the fast orbit feedback of the Elettra storage ring will be presented.

	W.T. Kitka, M.K. Falowski, A.M. Marendziak, N. Olszowska, M. Zając NSRC SOLARIS, Kraków, Poland
	NSRC SOLARIS is a 1.5 GeV third generation light source constructed at Jagiellonian University in Kraków, Poland. The machine was commissioned in April 2016 and operates in decay mode. Two beamlines PEEM/XAS and UARPES were commissioned in 2018 and they have opened for conducting research in fall 2018. Two more beamlines (PHELIX and XMCD) are installed now and will be commissioned soon. Due to small size of the team and many concurrent tasks, automation is very important. Automating many tasks in a quick and effective way is possible thanks to the control system based on TANGO Controls and Python programming language. With facadevice library the necessary values can be easily calculated in real-time. Beam position correction with PID controller at PEEM/XAS and UARPES beamlines, alarm handling in SOLARIS Heating Unit Controller and real-time calculation of various vacuum parameters are shown as examples.

MOPHA153	SoC Technology for Embedded Control and Interlocking Within Fast Pulsed Systems at CERN	controls, software, hardware, FPGA	592
	P. Van Trappen, E. Carlier, M. Gauthier, N. Magnin, E.J. Oltedal, J. Schipper CERN, Geneva, Switzerland
	The control of pulsed systems at CERN requires often the use of fast digital electronics to perform tight timing control and fast protection of high-voltage pulsed generators. For the implementation of such functionalities, a FPGA is the perfect candidate for the digital logic, however with limited integration potential within the control system. The market push for integrated devices, so called System on a Chip (SoC) - a tightly coupled ARM processing system and specific programmable logic in a single device, has allowed a better integration of the various components required for the control of pulsed systems. This technology is used for the implementation of fast switch interlocking logic, integrated within the CERN control framework by using embedded Linux running a Snap7 server. It is also used for the implementation of a lower-tier communication bridge between a front-end computer and a high fan-out multiplexing programmable logic for timing and analogue low-level control. This paper presents these two projects where the SoC technology has been deployed and discusses possible further applications within distributed real-time control architecture for distributed pulsed systems.

TUCPL02	Processing System Design for Implementing a Linear Quadratic Gaussian (LQG) Controller to Optimize the Real-Time Correction of High Wind-Blown Turbulence	controls, software, optics, Linux	761
	M. Kim, S.M. Ammons, B. Hackel, L. Poyneer LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 with document release number LLNL-PROC-792238. LLNL has developed a low latency, real-time, closed-loop, woofer-tweeter Adaptive Optics Control (AOC) system with a feedback control update rate of greater than 16 kHz. The Low-Latency Adaptive Mirror System (LLAMAS) is based on controller software previously developed for the successful Gemini Planet Imager (GPI) instrument which had an update rate of 1 kHz. By tuning the COTS operating system, tuning and upgrading the processing hardware, and adapting existing software, we have the computing power to implement a Linear-Quadratic-Gaussian (LQG) Controller in real time. The implementation of the LQG leverages hardware optimizations developed for low latency computing and the video game industry, such as fused multiply add accelerators and optimized Fast Fourier Transforms. We used the Intel Math Kernel Library (MKL) to implement the high-order LQG controller with a batch mode execution of 576 6x6 matrix multiplies. We will share our progress, lessons learned and our plans to further optimize performance by tuning high order LQG parameters.

TUCPL05	ESRF-Double Crystal Monochromator Prototype - Control Concept	controls, SRF, feedback, laser	776
	M. Brendike, R. Baker, G. Berruyer, L. Ducotté, H. Gonzalez, C. Guilloud, M. Perez ESRF, Grenoble, France
	The ESRF-Double Crystal Monochromator (ESRF-DCM) has been designed and developed in-house to enable spectroscopy beamlines to exploit the full potential of the ESRF-EBS upgrade. To reach concomitant beam positioning accuracy and beam stability at nanometer scale with a reliable, robust and simple control system, a double cascaded control architecture is implemented. The cascade is comprised of three modes: classic open loop actuation, an optimized open loop mode with error mapping, and closed loop real-time actuation. Speedgoat hardware, programmable from MATLAB/SIMULINK and running at 10 kHz loop frequency is used for the real-time mode. From the EBS startup 2020, the ESRF plans to deploy BLISS – the new BeamLine Instrumentation Support Software control system – for running experiments. An interface between Speedgoat hardware and BLISS has therefore been developed. The DCM and its control architecture have been tested in laboratory conditions. An overview of the concept, implementation and results of the cascaded control architecture and its three modes will be presented

	Funding: Argonne National Laboratory’s work was supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract DE-AC02-06CH11357 APS Upgrade multi-bend achromat accelerator (MBA) uses state-of-the-art embedded controllers coupled to various technical subsystems. These controllers have the capability to collect large amounts of fast data for statistics, diagnostics, or fault recording. At times, continuous real-time acquisition of this data is preferred, which presents a number of challenges that must be considered early on in the design; such as network architecture, data management and storage, real-time processing, and impact on normal operations. The design goal is selectable acquisition of turn-by-turn BPM data, together with additional fast diagnostics data. In this paper we discuss engineering specifications and the design of the MBA Data Acquisition System (DAQ). This system will interface with several technical subsystems to provide time-correlated and synchronously sampled data acquisition for commissioning, troubleshooting, performance monitoring and fault detection. Since most of these subsystems will be new designs for the MBA, defining the functionality and interfaces to the DAQ early in the development will ensure the necessary components are included in a consistent and systematic way.

	Funding: E.S.O. This paper presents the development of the Miniscule ELT (MELT) Control Software. MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts. *MELT - An optomechanical emulation testbench for ELT wavefront control and phasing strategy

WEMPR003	Exploring Embedded Systems’ Dedicated Cores for Real-Time Applications	controls, interface, hardware, operation	1036
	P.H. Nallin, J.G.R.S. Franco, R.C. Ito, A.R.D. Rodrigues LNLS, Campinas, Brazil
	Developments and research in high technology leads to powerful and sophisticated machines which are highly important for many scientific fields. Considering real-time applications, however, these systems tend to become non-deterministic and users may find themselves inside a not completely controllable environment. Exploring open-hardware single board computers with a system-on-a-chip which usually runs an operational system on their main processor(s) and also have real-time units is a good alternative. These real-time units are designed as a microcontroller embedded on the chip where a firmware is loaded, runs concomitantly and exchanges data with the main system. As a result, it is possible to achieve performance increase, high temporal resolution and low latency and jitter, features that are widely desired for controls and critical data acquisition systems. This system architecture allows moving real-time data into high level servers, such as Redis (Remote Dictionary Server) and EPICS, easily. This paper introduces and shows uses of Beaglebone Black, an inexpensive single-board computer, its Programmable Real-Time Units (PRUs) and data sharing with Redis data structure.

WEPHA046	EtherCAT Open Source Solution at ESS	controls, EPICS, PLC, ion-source	1195
	J. Etxeberria, J.H. Lee, A. Sandström ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility being built in Lund, Sweden. The Integrated Control System (ICS) division at ESS is responsible for defining and providing a control system for all the ESS facility. ICS decided to establish open-source EtherCAT systems for mid-performance data acquisition and motion control for accelerator applications. For instance, EtherCAT will be used when the I/O system needs to be beam-synchronous; it needs to acquire signals in the kHz range; or needs to be spread across locations that are far from each other and would need cumbersome cabling, but still, belong to one system. Following the ICS guideline, Motion Control and Automation Group developed EtherCAT Motion Control (ECMC) which is based on EtherLab open-source master. This solution was focused on Motion Control applications, but finally, data acquisition systems will be integrated into EPICS using the same approach. In this paper, we will present the ECMC solution and analyze its features showing some real applications at ESS.

WESH3002	Control System for Fast Components of Electron Beam Welding Machines	controls, EPICS, electron, experiment	1516
	A.V. Gerasev, P.B. Cheblakov BINP SB RAS, Novosibirsk, Russia
	Modern electron beam machines for different applications including welding, additive technologies and etc. consist of many different subsystems, which should be controlled and monitored. They could be divided by so-called fast and slow subsystems. Slow subsystems allow reaction time to be around couple of seconds that can be implemented using PC. Fast subsystems require time to be around hundreds of microseconds combined with flexible logic. We present an implementation of such fast system for mechanical moving platform and electron beam control. The core of this system is single board computer Raspberry Pi. We employed a technique of fast waveform generation using Raspberry Pi on-chip DMA to manipulate stepper motors. Raspberry Pi was equipped by external CAN controller to operate an electron beam via CAN DACs. Special software was developed including libraries for low- and high-level technical process control written in C and Rust; and in-browser graphical user interface over HTTP and WebSockets. Finally, we assembled our hardware inside standard 19-inch rack mount chassis and integrated our system inside experimental electron beam machine infrastructure.

	T. D’Ottavio, P.S. Dyer, J. Piacentino, M.R. Tomko BNL, Upton, New York, USA
	NuPIC (Numenta Platform for Intelligent Computing) is an open-source computing platform that attempts to mimic neurological pathways in the human brain. We have used the Python implementation to explore the utility of using this system to detect anomalies in both stored and real-time data coming from the controls system for the RHIC Collider at Brookhaven National Laboratory. This paper explores various aspects of that work including the types of data most suited to anomaly detection, the likelihood of developing false positive and negative anomaly results, and experiences with training the system. We also report on the use of this software for monitoring various parts of the controls system in real-time.

We used the Intel Math Kernel Library (MKL) to implement the high-order LQG controller with a batch mode execution of 576 6x6 matrix multiplies. We will share our progress, lessons learned and our plans to further optimize performance by tuning high order LQG parameters.

The ESRF-Double Crystal Monochromator (ESRF-DCM) has been designed and developed in-house to enable spectroscopy beamlines to exploit the full potential of the ESRF-EBS upgrade. To reach concomitant beam positioning accuracy and beam stability at nanometer scale with a reliable, robust and simple control system, a double cascaded control architecture is implemented. The cascade is comprised of three modes: classic open loop actuation, an optimized open loop mode with error mapping, and closed loop real-time actuation. Speedgoat hardware, programmable from MATLAB/SIMULINK and running at 10 kHz loop frequency is used for the real-time mode. From the EBS startup 2020, the ESRF plans to deploy BLISS – the new BeamLine Instrumentation Support Software control system – for running experiments. An interface between Speedgoat hardware and BLISS has therefore been developed. The DCM and its control architecture have been tested in laboratory conditions. An overview of the concept, implementation and results of the cascaded control architecture and its three modes will be presented

APS Upgrade multi-bend achromat accelerator (MBA) uses state-of-the-art embedded controllers coupled to various technical subsystems. These controllers have the capability to collect large amounts of fast data for statistics, diagnostics, or fault recording. At times, continuous real-time acquisition of this data is preferred, which presents a number of challenges that must be considered early on in the design; such as network architecture, data management and storage, real-time processing, and impact on normal operations. The design goal is selectable acquisition of turn-by-turn BPM data, together with additional fast diagnostics data. In this paper we discuss engineering specifications and the design of the MBA Data Acquisition System (DAQ). This system will interface with several technical subsystems to provide time-correlated and synchronously sampled data acquisition for commissioning, troubleshooting, performance monitoring and fault detection. Since most of these subsystems will be new designs for the MBA, defining the functionality and interfaces to the DAQ early in the development will ensure the necessary components are included in a consistent and systematic way.

This paper presents the development of the Miniscule ELT (MELT) Control Software. MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts.

Developments and research in high technology leads to powerful and sophisticated machines which are highly important for many scientific fields. Considering real-time applications, however, these systems tend to become non-deterministic and users may find themselves inside a not completely controllable environment. Exploring open-hardware single board computers with a system-on-a-chip which usually runs an operational system on their main processor(s) and also have real-time units is a good alternative. These real-time units are designed as a microcontroller embedded on the chip where a firmware is loaded, runs concomitantly and exchanges data with the main system. As a result, it is possible to achieve performance increase, high temporal resolution and low latency and jitter, features that are widely desired for controls and critical data acquisition systems. This system architecture allows moving real-time data into high level servers, such as Redis (Remote Dictionary Server) and EPICS, easily. This paper introduces and shows uses of Beaglebone Black, an inexpensive single-board computer, its Programmable Real-Time Units (PRUs) and data sharing with Redis data structure.

ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility being built in Lund, Sweden. The Integrated Control System (ICS) division at ESS is responsible for defining and providing a control system for all the ESS facility. ICS decided to establish open-source EtherCAT systems for mid-performance data acquisition and motion control for accelerator applications. For instance, EtherCAT will be used when the I/O system needs to be beam-synchronous; it needs to acquire signals in the kHz range; or needs to be spread across locations that are far from each other and would need cumbersome cabling, but still, belong to one system. Following the ICS guideline, Motion Control and Automation Group developed EtherCAT Motion Control (ECMC) which is based on EtherLab open-source master. This solution was focused on Motion Control applications, but finally, data acquisition systems will be integrated into EPICS using the same approach. In this paper, we will present the ECMC solution and analyze its features showing some real applications at ESS.

Modern electron beam machines for different applications including welding, additive technologies and etc. consist of many different subsystems, which should be controlled and monitored. They could be divided by so-called fast and slow subsystems. Slow subsystems allow reaction time to be around couple of seconds that can be implemented using PC. Fast subsystems require time to be around hundreds of microseconds combined with flexible logic. We present an implementation of such fast system for mechanical moving platform and electron beam control. The core of this system is single board computer Raspberry Pi. We employed a technique of fast waveform generation using Raspberry Pi on-chip DMA to manipulate stepper motors. Raspberry Pi was equipped by external CAN controller to operate an electron beam via CAN DACs. Special software was developed including libraries for low- and high-level technical process control written in C and Rust; and in-browser graphical user interface over HTTP and WebSockets. Finally, we assembled our hardware inside standard 19-inch rack mount chassis and integrated our system inside experimental electron beam machine infrastructure.

NuPIC (Numenta Platform for Intelligent Computing) is an open-source computing platform that attempts to mimic neurological pathways in the human brain. We have used the Python implementation to explore the utility of using this system to detect anomalies in both stored and real-time data coming from the controls system for the RHIC Collider at Brookhaven National Laboratory. This paper explores various aspects of that work including the types of data most suited to anomaly detection, the likelihood of developing false positive and negative anomaly results, and experiences with training the system. We also report on the use of this software for monitoring various parts of the controls system in real-time.
