摘要
针对交流传动数字控制系统的性能在很大程度上依赖于控制器的处理速度的特点,提出采用现场可编程门阵列FPGA来解决算法复杂的问题,介绍了三电平SVPWM的拓扑结构和算法,描述了采用FPGA的实现方法。仿真和试验表明:仿真与试验波形是一致的,FPGA可以提高控制器处理速度。
According to the performance of AC-driving digital control system greatly depends on the process speed of controller, fi eld programmable gate array(FPGA) was introduced to reduce the control period. Three-levels space vector pulse width modulation(SVPWM) topological structure and algorithm was introduced, and its realization with FPGA was described. The simulation and experiment results showed coincidence, and the FPGA could improved the procession speed of the controller.
