PWM rectifier research based on sliding mode variable structure control

Proposed a three-phase voltage PWM rectifiers control plan based on the sliding mode variable structure control theory. After simulate confirmation we can see that the sliding mode variable structure control system has a good robustness and good dynamic performance. At the same time established the three-phase voltage PWM rectifiers control system based on PI algorithm. After simulate confirmation we can also know that its disturbance rejection performance is poor. After comparing the two plans, we can get the conclusion that the three-phase voltage PWM rectifiers control system based on sliding mode variable structure control theory is better than the system based on PI Algorithm.
