An improved model predictive control of an inverter with LC filter

Abstract

In this paper, a new control method based on model predictive controller (MPC) is proposed to control a three phase inverter with LC filter. The proposed method is very similar to conventional MPC in algorithm and simulation and only adds one calculation step for selection of the optimum voltage vector which minimizes the cost function. Simulation results show the superiority of this method for linear and nonlinear load in comparison with the conventional one.
