This article studies the sensorless speed regulation problem for a surface-mount permanent magnet synchronous motor system. A new nonsmooth observer scheme is proposed to estimate the rotor position, speed, and lumped disturbance of the system. Based on the estimated information, a composite speed controller is designed using the nonsmooth control technique in the feedback design and the estimated value of disturbance in the feedforward compensation. Rigorous analysis using Lyapunov theory guarantees the stability of the closed-loop system and shows that the proposed method enhances the disturbance rejection property of the system. Simulation tests and experiment results verify the effectiveness of the proposed method.
The sensorless speed regulation problem for a surface-mount permanent magnet synchronous motor system is studied in this article. First, a new nonsmooth observer scheme is proposed to estimate the rotor position, speed, and lumped disturbance of the system. Based on the estimated information, a composite speed controller is then designed, in which the nonsmooth control technique is employed in the feedback design, and the estimated value of disturbance is used in the feedforward compensation. By Lyapunov theory, rigorous analysis guarantees the stability of the closed-loop system and shows that the proposed method can enhance the disturbance rejection property of the system. Finally, simulation tests and experiment results are given to verify the effectiveness of the proposed method.
