Analysis and Simulation of Single Phase Inverter Controlled By Neural Network

Abstract

This paper presents the analyses and design of Neural Network (NN) control of a single phase voltage source inverter with an L-C filter using only voltage sensor. A multiple feedback loop PI (Proportional-Integral) controller for PWM (pulse width modulation) inverter is built by root-locus method then simulated using Matlab (Simulink). The proposed NN is traind off-line using the patterns obtained from the simulated inverter with multiple loop PI (Proportional-Integral) controllers. Simulation results show that the proposed NN control can achieve low total harmonic distortion under linear loading condition, small steady state error and good dynamic response under any disturbance change in load. A hardware single phase inverter with programmed pulse width modulation control based on microcontroller is built and implemented with resistive load.
