HYBRID FUZZY LOGIC AND VECTOR CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE FOR ELECTRIC VEHICLE

Abstract

This paper presents the modelling and the control of a Permanent Magnet Synchronous Motor (PMSM) speed used in an electric vehicle. The classical vector control technique is enhanced using a specific Fuzzy Logic Controller FLC instead of a simple PI, IP or PID control. These classical controllers need the adjustment of controller gains. The determination the gains is not easy and needs to be adjusted if the operating conditions change. The optimization problem of regulators IP parameters used in the vector control method, has been solved by using a Fuzzy Logic. The FLC can be dedicated entirely to vector control of PMSM and it offers a robust and a realizable controller acting as a non linear (and optimized) PID. Than, the combination of fuzzy control strategy with vector controlled can give a good combination. In order to validate the simulation results, a comparison between the results obtained by classical vector control and the presented hybrid controller using FLC obtained by Matlab/Simulink software tool is included.
