论文摘要
提出了一种自适应的超级扭曲滑动模式观察者，用于在电融合伺服系统（EHSS）中进行故障重建，以接收有界限的有界扰动。目的是在经典的滑动模式观察者中解决具有挑战性的问题：颤抖的效果，观察者收益的保守主义，对故障分布和不确定性的强烈条件。在本文中，提出的超级扭曲滑动模式观察者放松了对不确定性和断层分布的条件，并且增益适应定律导致消除观察者的增益高估并减轻聊天效果。在使用滑动模式技术的等效输出 - 解析功能之后，提出了故障重建策略。提出了实验结果，证实了所提出的自适应超级倾斜观察者的有效性，以实现电湿度伺服系统中精确的断层重建。
An adaptive-gain super-twisting sliding mode observer is proposed for fault reconstruction in electro-hydraulic servo systems (EHSS) receiving bounded perturbations with unknown bounds. The objective is to address challenging problems in classic sliding mode observers: chattering effect, conservatism of observer gains, strong condition on the distribution of faults and uncertainties. In this paper, the proposed super-twisting sliding mode observer relaxes the condition on the distribution of uncertainties and faults, and the gain adaptation law leads to eliminate observer gain overestimation and attenuate chattering effects. After using the equivalent output-error-injection feature of sliding mode techniques, a fault reconstruction strategy is proposed. The experimental results are presented, confirming the effectiveness of the proposed adaptive super-twisting observer for precise fault reconstruction in electro-hydraulic servo systems.
