In Kyoto University Research Reactor Institute (KURRI), a fixed-field alternating gradient (FFAG) proton accelerator complex, which is consists of the three FFAG rings, had been constructed to make an experimental study of accelerator driven sub-critical reactor (ADSR) system with spallation neutrons produced by the accelerator. The world first ADSR experiment was carried out in March of 2009. In order to increase the beam intensity of the proton FFAG accelerator, a new injection system with H− linac has been constructed in 2011. To deal with these developments, a control system of these accelerators should be easy to develop and maintain. The first control system was based on LabVIEW and the development had been started seven years ago. Thus it is necessary to update the components of the control system, for example operating system of the computer. And the first control system had some minor stability problems and it was difficult for non-expert of LabVIEW to modify control program. Therefore the EPICS toolkit has been started to use as the accelerator control system in 2009. The present control system of the KURRI FFAG complex is explained.
