SIMULATOR OF GLOBAL ORBIT FEEDBACK SYSTEM FOR PLS USING EPICS

摘要

We have carried out the basic research for the accelerator and tokamak control system based on the Experimental Physics and Industrial Control System (EPICS). The EPICS is used widely in the accelerator systems where the hard real-time field, wide range and large integrated facilities are required. We have used the process database and the state notation language (SNL) in the EPICS to develop the simulator which represents as a virtual machine. In this paper, we introduce the simulator of the global orbit feedback system as an example. This simulates the global orbit feedback system under the constraint conditions for Pohang Light Source (PLS) storage ring. We describe the details of the feedback algorithm and the realization of the simulator.
