Model Predictive Control Technique of Voltage Source Inverter for Linear and Non Linear Load

This research work presents a non-conventional and effortless conversion of DC to AC voltage using a new method called Model Predictive Control which is also known as MPC with a LC Filter to reduce the harmonics in the waveforms for linear and non-linear loads using MATLAB Software. The Total Harmonic Distortion is very important in deciding the quality of the inverter output waveforms. The utilization of an Inverter with an output LC filter grants for the production of sinusoidal voltages with reduced harmonic distortion. The model predictive controller predicts the output voltages for all the feasible switching states produced by inverter. Then a cost function is utilized as a benchmark for choosing the switching state. The results show that the model predictive control method controls successfully the output voltage and performs very good when compared to conventional methods. The simulation results for balanced and unbalanced loads are performed using Matlab/Simulink tools, verifying the feasibility and good performance of the proposed control system.
