Twisting algorithm second order sliding mode control for a synchronous reluctance motor

This paper shows the design of a twisting algorithm second order sliding mode controller (SOSMC) for a synchronous reluctance motor. The second order sliding mode control is an effective tool for the control of uncertain nonlinear systems since it conquers the main shortcomings of the conventional sliding mode control, namely, the large control effort and the chattering effect. Its theory implies simple control laws and assures an improvement of the sliding accuracy with respect to conventional sliding mode control. This paper proposes a novel scheme that based on the technique of twisting second order sliding mode control. First, the SOSMC is obtained by mathematics. Finally, the proposed method is verified by simulation. The proposed SOSMC shows the robustness for the motor parameters variation and the development of chattering effect.
