针对状态不可用的非线性多变量系统，设计了一种稳定的自适应模糊滑模控制器。当系统状态未知时，利用半高增益观测器估计的状态，结合动态滑模，构造输出反馈模糊控制器。证明了在跟踪误差趋近于零的情况下，可以实现一致渐近输出反馈镇定。给出了一个非线性系统仿真算例，验证了该控制器的有效性。
A stable adaptive fuzzy sliding-mode controller is developed for nonlinear multivariable systems with unavailable states. When the system states are not available, the estimated states from a semi-high gain observer are used to construct the output feedback fuzzy controller by incorporating the dynamic sliding mode. It is proved that uniformly asymptotic output feedback stabilization can be achieved with the tracking error approaching to zero. A nonlinear system simulation example is presented to verify the effectiveness of the proposed controller.
