Torque Ripples Minimization In Five-level Dtc Based Im Drive Using Anfis Controller



Authors : Benbouhenni Habib .

Abstract

This paper presents a five-level direct torque control (DTC) is applied to an induction motor using ANFIS. The DTC is an advanced and simple control method has many advantages over other variable frequency control methods, but it has a common disadvantage of high torque and high flux ripples. To overcome this problem a torque hysteresis band with variable amplitude is proposed based on ANFIS. The ANFIS proposed controller is shown to be able to reduce the torque, current and stator flux ripples and to get better performance of the motor. The validity of the proposed controls scheme is verified by simulation tests of an induction motor. The stator current, stator flux and torque are determined and compared with the above technique
