A New Control Strategy of Three Phase Voltage Source PWM Rectifiers

In order to improve the properties of three phase voltage source PWM rectifiers, this paper proposes a new control strategy based on port-controlled Hamiltonian with dissipation (PCHD) model and Interconnection and Damping Assignment Passivity Based Control (IDA-PBC). Compared with other strategies, the rectifier has more dynamic and static performances by using the new strategy. Because of utilizing IDA-PBC to design passivity based controller, the stable state performance and robustness against the load's disturbance of PWM rectifiers are both improved. The results of simulation show feasibility of this new strategy.
