When the permanent magnet linear synchronous motor (PMLSM) direct drive system, the system has the characteristics of nonlinear, motor parameter time-variance and vulnerable disturbance, an adaptive sliding mode controller based on neural network is designed. The controller consists of two neural networks, one is used for sliding equivalent control and the other for sliding switch control, so as to effectively guarantees the system fast tracking performance for a given signal. The controller can restrain the system parameters perturbation and external resistance changes, and weakening the sliding mode control system chattering. The simulation results show that the adaptive sliding mode controller based on neural network can improve the system robustness for parametric perturbation and external disturbance, and possess better dynamic stability and tracking performance
