A second order sliding mode control design of a switched reluctance motor using super twisting algorithm

Abstract A novel robust technique for speed control application of variable reluctance motor is proposed. The suggested scheme is model based and uses a mathematical model of an SR motor, and Second Order Sliding Mode Control (SOSMC) with super-twisting algorithm. Sliding mode controllers for SR motor were reported before but super twisting SOSMC have an added advantage of reduced chattering which is one of the main focuses of this work. The proposed controller gives fast dynamic response with no overshoot and nearly zero steady state error. The effectiveness of the proposed controller and its robustness to parameter variations is also confirmed by simulation results.
