Abstract :
In this paper, model predictive control is applied to control a three-phase inverter. Model predictive control (MPC) is known for its simplicity and ease of use. The discussed inverter is generating pure sinusoidal voltages for sensitive applications such as uninterruptable power supply systems with low voltage total harmonic distortion (THD) demand. This method uses the model of the system to predict the behavior of the voltage on the next sampling interval for each possible switching state. A cost function is also used to decide which switching state to be applied based on minimizing the voltage deviations from the reference value and switching losses. Simulations have been done using PSCAD/MATLAB interfacing and results show the feasibility of MPC to control inverters feeding linear, nonlinear or unbalanced loads.
