英文摘要：

Basing on energy-shaping and port-controlled Hamilton control, the model and controller of three-phase voltage source PWM rectifier are presented. First of all, a PCH mathematical model of threephase voltage source PWM rectifier is established in the d-q rotation frames. Then, according to the target of the controller design, the desired equilibrium point of the system is obtained. Using the energy-shaping theory of intereonnection and damping assignment, the PCH feedback control theory of three-phase voltage source PWM rectifier is given. Feedback stabilization controller is designed through energy-shaping and matching the parameter, the stability of equilibrium point is analyzed finally. The simulation results show that this method can make PWM rectifier run with unit power factor, the output DC voltage stabilize on the desired value with the fast dynamic response. The characteristics meet the design demands.
