Permanent-Magnet Synchronous Motor is a multivariable nonlinear system with over-coupling and very sensible to outer disturbance and inner perturbance. To improve robustness of the servo systems, the method of Sliding Mode Control is introduced and a simple controller based on the algorithm of sliding mode control is developed in this paper. The simulation and experiment results demonstrate that the sliding mode controller designed is feasible and valid. It can offer a valid approach to the implementation of Permanent-Magnet Synchronous Motor servo systems.

Aiming at the parameter uncertainty and load torque disturbance of permanent magnet synchronous motor system, a terminal sliding mode control algorithm for permanent magnet synchronous motor based on the reaching law is proposed. First, a sliding mode control algorithm for sliding mode reaching law is proposed, which can dynamically adapt to the changes in system state. Second, a sliding mode disturbance observer is designed to estimate the lumped disturbance in real time and to compensate the controller for disturbance. On this basis, an online identification method based on disturbance observer for viscous friction coefficient and moment of inertia is used to reduce the influence of parameter uncertainty on the control system. Simulation and experimental results show the effectiveness of the method.
