In this paper the position control of a switched reluctance motor using backstepping design with adaptive action is proposed. First, a backstepping design for position control of SRM is proposed. Finally, an adaptive backstepping controller is investigated for a class of nonlinear system to tackle the nonlinear control problems with modelling uncertainties, plant parameters variations and external disturbances. The proposed scheme gives fast dynamic response with no overshoot and zero steady-state error. To show the validity and the effectiveness of the control method, simulations are performed for the position control of a switched reluctance motor. The simulation results show that the controller designed is more effective than the conventional backstepping controller in enhancing the robustness of control systems with high accuracy.
