    Abstract
  • A high-speed real-time dynamic power control system based on an open source platform has been developed to satisfy the multi-platform energy extraction requirements of the main loop dynamic power supply in a proton therapy facility. The control system uses a Beaglebone based open-source platform as the top-level hardware interface, the controller with Field Programmable Gate Array (FPGA) as the core as the underlying hardware interface, and uses a distributed Experiment Physics and Industrial Control System (EPICS) for remote control. This system can transmit the output reference current waveform data of any dynamic power source in real time, and controls the dynamic power source to output according to the preset current waveform combined with the timing system and the interlocking system, and realizes the energy extraction of multiple platforms. Experimental results show that the control system can achieve a maximum of 100 000 instructions per second and zero error rates for millions of data transmissions. In addition, the system structure is flexible and extensible, and it can be served as a universal control platform.
