ANALYSIS OF DIRECT TORQUE CONTROL OF INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR USING PID AND FUZZY LOGIC CONTROLLERS

Abstract

This paper deals with the novel modified
direct torque control (MDTC) scheme based on space
vector modulation for interior permanent magnet
synchronous motor drive . The torque and flux ripples are
greatly reduced compared with the conventional direct
torque control scheme. The proposed MDTC for interior
permanent magnet synchronous motor is modelled using
Matlab/ simulink. The comparative results show that the
FLC is more robust and, hence, found to be a suitable
replacement of the PID controller for the high
performance industrial drive applications.
