Direct Torque Control of PMSM Based on Model Free iPI Controller
In conventional PMSM DTC system, the electromagnetic torque displays the excellent dynamic performance. While, the dynamic performance of the speed is not satisfying. In this paper, the model free intelligent proportional-integral controller is designed to improve the dynamic performance of the speed. The purpose of this work is to compare the proposed controller with the classical PI controller for the dynamic performance of the speed. Simulation results show the effectiveness of the proposed controller in ameliorating the dynamic performance of the speed.
