Closed Loop – PI Control of a Single Phase Induction Motor Using SPWM

Kuheli Ghosh Goswami, Amit Ghosh

Abstract


In this paper we discuss the speed control of a single phase induction motor by proportional integral control. The PI controller fuses the properties of the P and I controllers. It shows a maximum overshoot and settling time similar to the P controller but no steady-state error. The output of the inverter has been smoothen by using LC filter. THIPWM techniques have lower total harmonic distortion than the SPWM technique and SVPWM have much lower THD than that of THIPWM. The THIPWM can increase the fundamental output voltage by 15.5% over the SPWM technique and SVPWM more than that. SPWM Simulation results are obtained using MATLAB / Simulink environment for effectiveness of the study.
