Switching Control of PWM Rectifier Based on Interconnection and Damping Assignment
To solve the limitation of single controller,the switching Hamiltonian system of Three-phase PWM Rectifier is studied in this paper.First,controller of PWM rectifier is designed by using interconnection and damping assignment(IDA-PBC)method.It has been shown that a single IDA-PBC controller cannot coordinate the contradiction between the speed of response and the overshoot of output.When the value of damper injection is small,the system starts slow.While the value of damper injection is too big,the system has output voltage overshoot.Then,two different damping matrices are assigned and a tracking-error-driven switching law is proposed to improve the dynamic and static characteristics of the rectifier.The simulation results show that the proposed switching control can overcome the limitation of a single controller based on IDA-PBC and have better performance.
