摘要：
For driving load directly, the servo performance of PMLSM (Permanent Magnet Linear Synchronous Motor) is influenced by external perturbation seriously. SMC (Sliding Mode Control) has the advantage that it is not sensitive to the perturbation and parameters change. But the "chattering" phenomenon limits its application in reality. In this paper, an improved SMC scheme with time-variable sign function gain is proposed. It is designed for the essential reason which causes the "chattering" phenomenon. The effectiveness of the proposed scheme is demonstrated by simulation.
