摘要：

An robust control scheme on the model of surface permanent magnet synchronous motor, composing a sliding-mode controller and a sliding-mode observer, was presented in this paper. To elimate the effects of parameters variation and uncertainties, the controller was constructed instead of conventional PI controller as well as the self-adaptive rule was deduced using, Lyapunov stability theory. The required voltage and current for the desired speed was then solved. A sliding-mode observer was employed to estimate the rotor position and speed. The convergence condition and cotrolling rule for the estimated algorithm was also obtained by utilizing Lyapunov theory. Theoretical analyse proved the independence of parameters variation and uncertainties and showed the good robustness of the scheme. Computer simulations and the realization were done and results testified the effectiveness and correction of the proposed scheme
