IMPLEMENTATION OF DIGITAL PWM SPEED CONTROL STRATEGY FOR SURVIVABLE INDUCTION MOTOR DRIVES

Abstract

Induction machines have been widely used in a variety of industrial and residential applications. It is commonly used due to their compactness, reliability and low cost. There are different kinds of control techniques emerged in the past. The most commonly used control strategies are constant V/f control and vector control. Due to the complexity of these methods, the reliability can be reduced. In this proposed method the space vector pulse width modulation technique is used. The specific duty cycles of PWM which produces the phase voltages with different magnitude of phase windings is done. The conventional PI controller demoralizes the performance of the overall system. To overcome this problem fuzzy logic controller based intelligent controller is proposed. The performance of the intelligent controller has been inquired through digital simulation using MATLAB-SIMULINK software.
