	This paper describes the optimization work carried out to improve the performance of the LNLS UVX fast orbit feedback system. Black-box system identification techniques were applied to model the dynamic behavior of BPM electronics, orbit correctors, communication networks and vacuum chamber eddy currents. Due to the heterogeneity on the dynamic responses among several units of those subsystems, as well as variations on the static response matrix due to accelerator optics changes during operation, robust control techniques were employed to achieve appropriate closed-loop performance and robustness.

WEPGF128	Development Status of the Sirius Timing System	1007
	J.L.N. Brito, S.R. Marques, L.A. Martins, D.O. Tavares LNLS, Campinas, Brazil
	Sirius is a new low-emittance 3 GeV synchrotron light source under construction in Brazil by LNLS, scheduled for commissioning in 2018. Its timing system will be responsible for providing low jitter synchronized signals for the beam injection process as well as reference clocks and triggers for diverse subsystems such as electron BPMs, fast orbit feedback and beamlines distributed around the 518 meters circumference of the storage ring, Booster and Linac. It will be composed of Ethernet-configured standalone event generators and event receivers modules developed by SINAP through a collaboration with LNLS. The modules will be controlled by remote EPICS soft IOCs. This paper presents the system structure and the status of the development, some options for integrating it to the Sirius BPM MicroTCA platform are also discussed.
