ABSTRACT: In this paper, a novel control structure combing the adaptive backstepping (BS) and sliding mode (SM) control techniques to improve the performance and enhance the robustness of the vector control of six phase induction motor (SPIM) drives is proposed. The outer speed closed loop control uses the BS controller with the integral error tracking component added to improve its sustainability. Second order sliding mode controller is proposed for the inner current closed loop control to can effectively compensate for load disturbance in the system so the proposed method is more robust, stability and faster dynamics response, chattering free performance. The proposed speed control scheme is validated through Matlab-Simulink. The simulation results confirm the good dynamics and robustness of the proposed control algorithm based on (BS_SOSM) technique
