VSC Inverter with Fuzzy Controller for Non Linear and Unbalanced Loads
In this paper, model predictive control is applied tocontrol a three-phase inverter. Model predictive control (MPC)
isknown for its simplicity and ease of use. The discussed inverter isgenerating pure sinusoidal voltages for sensitive
applications. Such as uninterruptable power supply systems with low voltage total harmonic distortion (THD) demand. This
method uses themodel of the system to predict the behavior of the voltage on thenext sampling interval for each possible
switching state. A costfunction is also used to decide which switching state to be appliedbased on minimizing the voltage
deviations from the referencevalue and switching losses. Simulations have been done usingPSCAD/MA TLAB interfacing
and results show the feasibility ofMPC to control inverters feeding linear, nonlinear or un balanced loads.
