摘要
摘 要: 针对一类具有不确定性的非线性系统,提出了一种模糊趋近律滑模控制策略。将模糊逻辑控制与趋近律相结合,推导出模糊趋近律,该设计方法简单,控制算法容易实现。仿真结果表明,本文提出的方法不仅保留了滑模控制系统所具有的较强的鲁棒性优点,又使控制系统滑动模态的品质得到保证和改善,同时消除了系统的高频颤动。
A scheme of the sliding mode control based on fuzzy reaching law for a class of nonlinear systems with uncertainties is proposed in this paper. Since the proper fuzzy logic control is applied to the reaching law, the quality is improved. At the same time, the chatting phenomenon is avoided. Simulation results show that the control system exhibits not only strong robustness and better quality control but also avoiding the chatting phenomenon.
