Study on Fuzzy Control Type-2 of Induction Machine with broken bars Faults Using Direct Torque Control Approach

摘要

The aim of this paper is to investigate the performance of a DTC which is applied on three-phase induction motor drive system for high-performance industrial applications using a fuzzy logic (FL). The Direct Torque Control (DTC) is very good control scheme for dynamic performance and it is easy to implement and decoupling of motor variables along rotor flux axis is not required. The proposed DTC scheme uses the fundamental stator voltage vector for identification of sector for selection switching of vector to control stator flux and the torque. In this paper DTC proposed using a fuzzy logic controller. The proposed scheme is capable for enough degrees of freedom to control both electromagnetic torque and stator flux with very low ripple. The performance of this control method has been demonstrated by simulations performed using a versatile simulation package, Matlab/Simulink.
