Speed-assigned position tracking control of SRM with adaptive backstepping control

A novel speed-assigned method is applied to the position tracking control of switched reluctance motor ( SRM ). A speed control freedom can be drawn into the position control through speed assignment. Adaptive backstepping control is used to design the position controller for the SRM. The accuracy of position tracking of the SRM can be enhanced with speed assignment. A disturbance observer is further designed to enhance the estimation accuracy of the unknown load torque. Simulation results certify that the design scheme is right and effective.
