摘　　要：针对三相脉宽调制(pulse width modulation,PWM)整流器通常采用基于PI控制的双闭环控制系统性能比较差的问题,提出一种以滑模控制替代PI控制的新的双闭环控制方案。运用Matlab/Simpower工具完成了仿真模型的搭建,在此基础上进行了有针对性的对比仿真实验,结果表明三相PWM整流器的滑模控制系统具有更好的动态响应能力和抗干扰性。Aimed at the low dynamic behavior of the double closed-loop control system of three-phase PWM rectifier based on PI control,a new double closed-loop control scheme based on sliding-mode was proposed.The simulation model of the whole system was built between sliding-mode and classical double PI control by using Matlab/Simpower,and a pointed simulation experiment was conducted on this basis.The simulation results show that the three-phase PWM rectifier sliding-mode has good dynamic response and anti-interference performance.
