Design and Modelling of Speed Control of Three Phase IM based on PID Controller

Abstract

In a variable-speed drive system, speed control is usually required. A three-phase inverter provides variable voltage and frequency to this system. The speed of an induction motor supplied by such a three-phase inverter was controlled using PWM approach as well as a universal connection in this study. A control strategy was developed to regulate a dc voltage inverter's maximum dc bus voltage. Following vector control technology, direct torque control (DTC) is a superior, contemporary, and innovative form of AC machine drive control technology. The Texas instrument TMDSHVMTRPFCKIT is used to build a DTC scheme for Induction Motor Drive utilising the Space Vector Modulation (SVM) approach in this study. Due to its simple architecture, power reversal capabilities, and robust fault current protection of three-phase inverter supplied induction motor (IM) controls have been a popular option in medium-voltage applications. The direction of the rotor flux is also determined. The inductive vehicle's transient response is also carefully investigated.
