Fuzzy Logic Based Field Oriented Control Of Permanent Magnet Synchronous Motor

摘要

The present research is indicating that the Permanent magnet motor drive could become serious competitor to the induction motor drive for servo application.Further, with the evolution of permanent magnet materials and control technology, the Permanent Magnet Synchronous Motor (PMSM) has become a pronounced choice for low and mid power applications such as computer peripheral equipments, robotics, adjustable speed drives and electric vehicles due to its special features like high power density, high torque/inertia ratio, high operating efficiency, variable speed operation, reliability, and low cost etc.However, the main disadvantage of PMSM is the non-uniform variance in the developed torque.Vector controlled PMSM drive provides better dynamic response and lesser torque ripples.This paper proposes a Fuzzy logic control scheme for a PMSM drive driven by Field Oriented Control (FOC).The proposed scheme is developed in MATLAB/SIMULINK environment.Simulation results are generated for testing the performance validity of the control law.
