An Optimisation Framework for Induction Motor Power in Electric Vehicles Using Fuzzy Logic Control

Abstract: Energy efficiency plays a vital role in electric and hybrid vehicles (EVs) due to their limited energy storage capacity. Besides its excellent stability and low cost, minimizing losses enhances the efficiency of the induction motor. Furthermore, when operating below its maximum load, it may consume more power than necessary for its tasks. This study proposes a fuzzy logic control (FLC)-based method for applications in electric vehicles. The FLC controller is capable of conserving additional power and improving the initial current amplitude. The performance of the control was validated through simulation using the MATLAB/SIMULINK software program. The simulation results indicate a swift rejection of disturbances impacting the system and demonstrate superior performance outcomes in the time-domain response compared to the conventional proportional integral derivative controller. Consequently, the core losses of the induction motor are significantly reduced, thereby enhancing the efficiency of the driving system.
