A Study of a Three Phase Induction Motor Performances Controlled by Indirect Vector and Predictive Torque Control

Abstract

This paper compares two methods of a three phase induction motor speed control supplied by a two-level three-phase inverter, those are indirect vector control (IVC) and predictive torque control (PTC). The simulation results of both methods show that when given torque and certain reference speeds, either by using IVC or PTC the motor will provide torque response and speed according to the reference given. Both of these methods can also follow the reversal of motor rotation according to the reference speed dictated. In addition, the value of the effective stator current using both methods is the same. The steady state torque of PTC is achieved faster than IVC.
