摘要
滑模变结构制导律是一种强鲁棒性的制导律,对于系统的参数变化和外部的干扰具有理论上的完全鲁棒性。然而,滑模变结构制导律在滑模面上的高频抖振是其在实际应用当中的主要障碍。本文介绍了目前削弱滑模变结构制导律抖振的主要方法。重点介绍了模糊控制、RBF神经网络控制与滑模变结构控制相结合的智能滑模变结构制导律。智能滑模变结构制导律是解决抖振问题的发展方向。
Sliding mode variable structure guidance law is a strong robustness guidance law. It iscompletely robustness in theory even respect to system parameter variation and external disturbances.However the chattering of the sliding mode variable structure guidance law on the sliding mode is a mainobstacle in practical application. This paper introduces the main methods to weaken the chattering. Theintelligent sliding mode variable structure guidance law combines with fuzzy control theory and RBF neuralnetwork is emphasized. The future direction of chattering reduction is intelligent sliding mode variablestructure guidance law.
