摘　　要：提出了基于数字信号处理器(DSP)和现场可编程门阵列(FPGA)的开关磁阻电动机全数字控制系统,对DSP和FPGA的功能进行了分配。根据开关磁阻电动机的驱动要求,分析控制逻辑,由FPGA实现了电流斩波、角度位置和PWM电压斩波相结合的控制方案。仿真结果表明,设计的开关磁阻电动机调速系统具有高效、实时、动态性能好等优点。The DSP-and FPGA-based all-digital control system of switched reluctance motor（SRM） is proposed in this paper.The functions of DSP and FPGA are assigned in the system.According to the driving requirement of SRM,the control logic is analyzed.The control scheme that combines current chopping control（CCC）,angular position control（APC） and PWM voltage chopping control is realized by means of FPGA.The simulation result shows that the SRM all-digital control system designed in this paper has the advantages of high-efficiency,real-time and good dynamic performance.
