| Abstract | The permanent magnet synchronous motor (PMSM) has been widely used in position control applications. Its performance is not satisfactory due to the internal uncertainties and external load disturbance. To enhance the control performance of PMSM systems, a new method which has a fast performance and good robustness is proposed in this paper. First, a modified integral terminal sliding mode control is developed. It has a faster sliding surface and a continuous reaching law. Then the extended state observer technique is applied to measure the internal and external disturbances. Therefore, the disturbances can be compensated by a feedforward manner. Compared with other sliding mode methods, the proposed method has a faster response and a better robustness against system disturbances. In addition, the position tracking error can converge to zero in finite time. Simulation and experimental results reveal that a fast, high-precision and robust performance is realised under the proposed control method. |
