Abstract: The requirements of part of power supply control systems for the heavy ion accelerator were analyzed, and a real-time, efficient, multi-function control system was proposed and achieved. The key processing architecture of this system is based on a combination of a digital signal processor (DSP) and two field programmable gate array (FPGA) chips. The back-end of the system exchanges data with the system controller and other components in the industrial control chassis by the PXI bus interface and the FPGA. The front-end of the system can process control parameters of different power supplies and output the power through the direct digital synthesizer, analog to digital converter, digital to analog converter, and the control algorithm and mechanism realized in the DSP and FPGA. The two groups of fiber optical modules corresponding with the front-end FPGA can achieve the receiving and sending efficiently for the real-time data like synchronous event signal and the debugging of the platform.
