INTELLIGENT CONTROL OF INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE
2009
This paper presents a novel fast speed response control strategy for the interior permanent magnet synchronous motor (IPMSM) drive system using intelligent control. As an intelligent controller, the Fuzzy Logic Controller (FLC) is considered in the present work. In this paper, a closed loop control system with FLC in the speed loop has been designed where the motor is fed from a six switch three phase (6S3Ph) pulse width modulation (PWM) inverter. The closed loop vector control technique is used in this work. The approach proposed here is based on a comparison between PI controller and FLC. Simulation of the drive system was carried out to study the performance of the motor drive. It is observed that the proposed fuzzy logic control methodology provides faster response than the conventional PI controller incorporated system.
