Adaptive Backstepping controller usuing to PMSM Speed Tracking Control

Abstract

In this paper, the speed control of a permanent magnet synchronous motor using an adaptive backstepping control design based on filed orientation is proposed. Firstly, the indirect field oriented control of permanent magnet synchronous motor (PMSM) is derived. Then, a novel adaptive backstepping control design technique is investigated to achieve a speed tracking objective under parameter uncertainties and disturbance of load torque. The effectiveness of the proposed control scheme is verified by numerical simulation. Simulation results clearly show that the proposed control scheme can track the speed reference signal generated by a reference model successfully under parameter uncertainties and load torque disturbance.
