摘　　要：利用遗传算法较强的鲁棒性以及FPGA在并行计算方面的巨大优势,以中国加速器驱动次临界系统(C-ADS)注入器Ⅱ的第四个超导加速组元(CM4)为例,开发了超导腔失效在线补偿FPGA程序,并使用束流动力学软件TRACEWIN对FPGA计算结果的可靠性进行验证。然后将其封装为IP核,以更通用的形式在嵌入式Linux系统中使用;同时,针对未来超导腔失效补偿系统的独立性、低延时的要求,应用MicroBlaze软核处理器编译了Linux系统和EPICS组件,在搭建的仿真通讯环境中验证了超导腔失效补偿系统的通信功能。Taking advantage of the robustness of genetic algorithm and the advantage of FPGA in parallel computing, we developed the cavity failure compensation program based on the Injector Ⅱ’s Cryogenic Module IV(CM4) of China Accelerator Driven Sub-critical System(C-ADS). The beam dynamics software TRACEWIN was used to verify the results got by the FPGA program, and the FPGA program was packed as an IP core to be used in a more general form in the embedded Linux system. In addition, considering the requirements of independence and low latency for the future superconducting cavity failure compensation system, Linux system and EPICS components are compiled for the MicroBlaze soft core processor, and the communication function of the superconducting cavity failure compensation system was verified in the built simulating communication environment.
