Performance Improvement Using Self-Tuning Fuzzy Logic Control with Application in LEV Using SRM

This work explores the application of switched reluctance motor (SRM) for light electric vehicle (LEV). A three phase, 12/8 SRM is used in LEV with proper control. The flux and torque profiles of the SRM, are experimentally achieved. A current control method using an improved self-tuning fuzzy logic controller (STFLC) is designed and implemented in the MATLAB®/Simulink platform. Self-tuning of the fuzzy logic controller (FLC) is achieved by a gain factor. The fuzzy rules for tuning the gain factor and for the control of SRM, are applied for the acceptable and efficient operation of SRM for LEV. A comparison in speed response between the conventional proportional integral (PI), FLC and STFLC, is performed and analyzed in detail.
