In this paper a neuro-fuzzy-sliding mode control (NFSMC) with extended state observer (ESO) technique is designed to ensure the traction of an electric vehicle with two separate permanent magnet synchronous motor (PMSM). Each PMSM systems ( source-converter-motor) are coupled to an electronic differential (ED) in order to compensate the tendencies of direction of the vehicle and maintain a steady speed by adjusting the difference in speed of each motor-wheel according to the direction in the case of a turn. To ensure the control and performance of the vehicle  a hybrid control scheme employs two types of controllers , neuro-fuzzy sliding mode control on the direct current loop and disturbance rejection control laws (ESO) on the Speed loop ,and quadrature current loop of the PMSM by taking into account the dynamic of the vehicle. Simulation under Matlab/Simulink to evaluate the efficiency and robustness of the proposed control method and ED on the closed loop system.
