Harmonic analysis of fractional order PID controlled induction motor with PV based SAF [articol]

Abstract

This paper deals with the reduction of source current harmonics in Fractional Order PID controlled induction motor with solar PV based SAF. The solar PV based zeta converter controlled shunt active filter (SAF) can regulate the source current harmonics in desired limits due to the presence of nonlinear loads. The comparative results of source current harmonic THD levels in the PID and FOPID controlled induction motor have been presented. In this proposed system suggested a new way of SAF connection at the supply end along with FOPID control. The proposed system is modeled and simulated using MATLAB/Simulink software. The Simulation results of FOPID controller give better performance than the traditional PID controller.
