摘要
针对一类非线性不确定系统,把自适应模型跟踪控制和模糊控制与趋近律相结合,提出一种新的自适应模糊滑模变结构控制方案。不仅消除了滑模变结构控制固有的高频颤动现象,对模型不确定性和外部干扰具有较强的鲁棒性,而且改善了系统到达段的品质,同时跟踪误差可收敛到零的一个邻域内。仿真结果也表明了该方案的正确性。
A new scheme of adaptive fuzzy sliding model variable structure control for a class of uncertain nonlinear system is presented, which is by incorporating adaptive model tracking control and fuzzy control with reaching law. It can not only eliminate the chattering of sliding model variable structure control and make system have strong robustness against model uncertainties and external disturbance, but can also improve the character of reaching segment and tracking errors converge to a range of zero. The simulation results show that the scheme is correct.
