摘要：
Model Predictive Control (MPC) method is proposed in this paper applied to a single phase grid-connected inverter. This method uses a state-space equation of the system to predict the next time value of current from the grid side by adjusting the duty ratio of inverter in each sampling period. The duty ratio which minimizes a cost function is selected. Then, taking advantage of the duty ratio to control the output current of single phase inverter. This scheme is easy to realize and its mathematical model is simple. This method is convenient compared with traditional control method of single phase inverter. There is no need to adjust PI parameters. The Simulation results show that the model predictive control can effectively predict the output current and the system performs very well.
