摘　　要：本文针对高精度伺服系统，提出一种离散自适应沿模跟踪控制策略。用李亚曾诺夫稳定性理论设计位置环自适应控制器，使系统在趋近滑楼平面的过程中始终跟踪理想的趋近过程，快速到达滑楼平面。通过在实际交流伺服系统中的应用，表明该控制方法使系统具有良好的鲁棒性、快速性和无超调，并显著地减小了抖振。This paper proposed a discrete sliding mode tracing scheme based on adaptive c0ntrol law for highaccuracy servo system. By using Lyapunov stability theory, the reaching process can be controlled to keep intracing an ideal process of a reference model so that the system can reach the sliding mode quickly and precisely.The successful application on an AC. servo system shows that this method effectively improves the robustnessand response speed of the system and reduces the chattering.
