High Performance Predictive Direct Torque Control Of Induction Motor Drives System

This paper presents a practical implementation for direct torque control of induction motor drive. Control system experiment is proposed using Digital Signal Processor. This control scheme directly determines the switching states of the inverter and gives optimal characteristics for stator flux and torque control. A simple switching pattern for direct torque control algorithm for induction motor drives has been presented. The main results with the simple approach are greatly reduced torque pulsations, constant and controlled switching frequency. Results show that the simulation meets the experimental results
