| Bibliography: | 41-1401/TM PWM rectifier; PCHD model; IDA-PB control; damping injection; PDE This paper establishes PCHD model of PWM rectifier in synchronous dq coordinates based on the Port-Controlled Hamiltonian Damping model equation. Using IDA-PB control and the function of the new damping injection and the power conservation principle of the system, it's easy to deduce the IDA-PB control law of PWM rectifier without solving PDE. And the stability of PWM rectifier is proven. The validity of the IDA-PB control law is verified by simulation and experiment. The results show that using the IDA-PB control by damping injection, PWM rectifier has good steady and dynamic property, as well as strong robustness.
