Abstract：DC/AC converter is inherently hybrid in structure. The dynamic characteristic of the converter is analyzed and from the view of control the optimization goal is given. In order to include the switches’ dynamic in the model the PWM period is divided into several subperiods. The switches’ states in each subperiod are judged by introduced auxiliary logic variables, which decided how the system evolved. The tool of HYSEDL is used to describe the converter and the mixed logic dynamic(MLD) model is obtained. Based on the model the predictive controller is designed。The numerical value solution is achieved by solving the corresponding mixed integer linear programming problem. The simulation results verify the validity of the model and the effectiveness of the proposed controller.
