TORQUE RIPPLE MINIMIZATION IN FIELD ORIENTED CONTROL IN PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE

Abstract

The Permanent Magnet Synchronous Motors are special electrical machines which can become a best replacement for Induction motor in the near future. The construction of the motor is similar to the induction motors where the stator is similar to these motors and the rotor consists of permanent magnets. A substantial air gap is generated and produced with the use of permanent magnets in the rotor for manufacturing highly competent and efficient motor drive for automation. The main disadvantage seen in these types of motors are the production of pulsation torque which increases the noise and vibration of the motor drive thereby reduces the efficiency of the drive. This paper discusses about various control techniques to reduce the torque pulsations in the motor by using the conventional PI controller and Fuzzy controller. The design and analysis of the various systems is done in MATLAB 2010b and the comparison is studied to analyse the best technique for torque ripple minimization in field oriented control in Permanent magnet synchronous motor drive.
