Abstract
The mathematical model of three-level PWM rectifier is a multi-input multi-output system of strongly coupled system. In industrial applications, PI controller is adopted as the main regulator of the rectifier, but parameter setting of the PI controller is of great impact on the system. In this paper, we put forward a method of applying LQR algorithm to the controller of the power inner loop, combined with the power mathematical mode of the three-level PWM rectifier. The feasibility and accuracy of the method is verified through the simulation.
