Disturbance Observer Based Terminal Sliding Mode Control Method for PMSM Speed Regulation System
This paper investigates the permanent magnet synchronous motor (PMSM)speed regulation system using terminal sliding mode control method.By introducing a non-singular terminal sliding mode manifold,a novel terminal sliding mode controller is designed for the speed loop.This controller can make the states not only reach the manifold in nite time,but also converge to the equilibrium point in nite time.Thus,the controller could make the motor speed reach the reference value in nite time,obtaining a faster convergence and a better tracking precision.Meanwhile,considering the large chattering phenomenon caused by high switching gains,a composite terminal sliding mode control method based on disturbance observer is proposed to reduce chattering.Through disturbance estimation for feed-forward compensation,the composite terminal sliding mode controller may take a smaller value for the switching gain without sacri cing disturbance rejection performance.Simulation results and comparisons are given to show the superiority of the proposed method.
