An electronic differential system using fuzzy logic speed controlled in-wheel brushless DC motors

Environmental issues and running out of fossil fuels has increased the interest in electric vehicles (EV). In this paper, an EV with independent rear two-wheel drive systems is presented. Two brushless DC motors (BLDCMs) with fuzzy logic speed controller (FLSC) were used in rear wheels. Ackermann-Jeantaud steering model was employed for electronic differential (ED) system. The proposed method was simulated using Matlab/Simulink. Simulations were carried out on straight and curved roads. Simulation results show that proposed ED system operates satisfactorily.
