Fuzzy Sliding Mode Controller for Direct Torque Control of Four-Wheel Drive Electrical Vehicle

To improve vehicle handling characteristics of Electric Vehicles (EV), recent system control studies make it possible to operate driving wheel torques separately have been carried out. In this paper a fuzzy sliding-mode controller based on the hybridization between fuzzy logic and sliding mode control has been applied for the Direct Torque Control (DTC) of 4 Wheel Drive Electric Vehicle (4WDEV). Using MATLAB Simulink environment, a comparison of simulation results, application of the FSMC and the Sliding Mode Control (SMC), proved that the application of the FSMC technique presents a better alleviation of the chattering phenomenon and increases trajectory tracking performance.
