JEE_V10_N1_RP4 Modeling of a Variable Speed Drive Using Adaptive Fuzzy System J.N. Chandra Sekhar G.V. Marutheswar Journal on Electrical Engineering 2230 – 7176 10 1 19 25 Direct Torque Control (DTC), Fuzzy Logic Control (FLC), Asynchronous Machine, Adaptive Fuzzy Control, Space Vector Modulation (SVM), Induction Motor (IM) This paper presents the operation of Space Vector Modulation (SVM) based DTC scheme for a Voltage Source Inverter fed Induction Motor Drive. Firstly, the performance of existing model is studied with Fuzzy Logic Controller. In order to incorporate better dynamic response, the discussed model is further simulated using Adaptive Fuzzy Controller. Simulations results obtained with these controllers are presented and compared. It may be inferred that Adaptive Fuzzy based model exhibit better operational features with regard to torque and flux response. The performance of this control method has been demonstrated by simulations done using MATLAB/SIMULINK tool. July - September 2016 Copyright © 2016 i-manager publications.
