Robust Intelligent Tracking Control Technique for Single-Phase SPWM Inverters

This paper presents a robust intelligent tracking-control technique which is subsequently applied to single-phase SPWM inverters. The proposed mixes advanced sliding mode control (ASMC) with grey-Markov model (GMM). allows the system state converge quickly origin in limited amount of time. Unfortunately, chattering problem frequently occurs when inverter suffers drastically from highly nonlinear or internal parameters changes. large power losses and high harmonic distortion emerge output. role that plays reduce ASMC during uncertainty overestimation, steady-state error caused by underestimation uncertainty. In conjunction GMM ASMC, fast transient response, low sinusoidal output-voltage reduced can be obtained. Simulation results are carried out MATLAB/Simulink. experimental have been validated through digital signal processors, enabling output effectively improve tracking speed performance.
