Investigation of transient performance of VSI-fed IM drives with SVPWM technique based on P, PI, and PID controllers

Abstract

This paper has been attempted to presents the investigation of transient performance of Voltage Source Inverter (VSI)-fed Induction Motor (IM) drives with Space Vector Pulse with Modulation (SVPWM) technique based on Proportional (P), Proportional Integral (PI), and Proportional Integral Derivative (PID) controllers. In general, the principle of operating a three phase IM indicates that the speed of the motor is directly related to the frequency of the supply. This fact has made the inverter-fed induction motor having a very common configuration in the majority of industrial applications. The VSI-fed IM drives are increasingly applied in many recent industrial applications that require excellent transient performance of drives. There is an increasing trend of using SVPWM because of their easier digital realization and better DC bus utilization capability. Advantages of lower harmonics and a higher modulation index in addition to the features of complete digital implementation by a single chip microprocessor, because of it flexibility of manipulation; SVPWM has increasing applications in power converters and motor control. Simulation results and discussions regarding with SIMULINK model of VSI-fed IM drives with SVPWM techniques based on P, PI, & PID controllers are obtained using MATLAB/SIMULINK environments for effectiveness of the proposed technique.
