MPC for 3-Phase Inverters:

This repository contains the codes for control a three-phase inverter with output LC filter using Model Predictive Control (MPC). The controller uses a discrete-time model of the system to predict the behavior of the output voltage for all possible switching states generated by the inverter. Then, a cost function is used as a criterion for selecting the switching state that will be applied during the next sampling interval. The simulations for MPC with only one-prediction step are presented under linear and nonlinear loads using MATLAB/Simulink tools.

Usage:

• For Linear loads (i.e., Resistive), type in the Command window, for instance:

>> clear all, clc, Ts = 30e-6; Vref = 200; Cfilter = 40e-6; Lfilter = 2.5e-3; Vdc = 500; Res = 100; 

Then, run the Simulink model (i.e., MPC_3Phase_Inverter.slx)

• For Non-Linear loads (i.e., diode-bridge rectifier), type in the Command window, for instance:

 >> clear all, clc, Rnload = 100; Cnload = 500e-6; Ts = 30e-6; Lfilter= 4.0e-3; Cfilter = 45e-6; Vdc = 520; Vref = 250;

Then again, run the Simulink model. Do not forget to uncomment and connect the Non-Linear load ;-)

• For HIL simulations using DSP, run the two .slx files in HIL MPC+DSP folder. For more information, kindly have a look at the MS Thesis.

Requirement:

This model was updated to be compatible with Matlab R2018a and the most recent versions.
