摘　　要：A digital low level radio frequency （LLRF） control system based on a high precision fieldprogrammable gate array （FPGA） is being developed for the stable operation of the upgraded direct currentsuperconductive （DC-SC） photocathode injector at Peking is described, including both the hardware and the internal University. The design of this LLRF control system algorithm. Analysis of disturbances shows that the system can achieve the requirement of ±0.1% for amplitude stability and ±0.1° for phase stability. Through experiments, preliminary results are presented in the paper.A digital low level radio frequency （LLRF） control system based on a high precision fieldprogrammable gate array （FPGA） is being developed for the stable operation of the upgraded direct currentsuperconductive （DC-SC） photocathode injector at Peking is described, including both the hardware and the internal University.
