Abstract：Aiming at the problems of low position tracking accuracy and poor anti-interference ability of permanent magnet linear synchronous motor （PMLSM），an integral terminal sliding mode control （ITSMC） based on non-smooth reaching law （NSRL） combined with Luenberger（LBG） observer control method was designed.The ITSMC was firstly established，which can well eliminate the steady state eror and ensure the system state to converge quickly in a limited time. The NSRL was used to replace the traditional sliding mode convergence law，which ensures the continuity of the output and reduces the system chater by virtue of its own structure. The LBG observer observes the load disturbances and feed-forward compensates them to the output of the controller to improve the robustness of the system. Finally， the proposed method was simulated and experimented，and the results show that the method improves the control accuracy and strengthens the robustness of the system compared with the traditional control method.
