中文摘要：
研究了非仿射非线性系统的模糊自适应H∞输出反馈跟踪．在非仿射非线性模型存在不确定的情况下，使用模糊自适应控制器对系统进行控制，并基于Lyapunov稳定性定理得出自适应律．通过解一个代数Riccati方程实现了H∞跟踪性能．估计状态通过引入高增益观测器得到，实现了系统的输出反馈控制．最后，通过对一个数值例子的仿真验证了算法的有效性．
英文摘要：
A fuzzy adaptive H∞ output feedback controller for non-affine nonlinear systems is studied. This paper considers uncertain or ill-defined non-affine nonlinear systems and employs a fuzzy logic adaptive controller to control the systems. Adaptive law is designed based on Lyapunov stability. H∞ tracking performance is achieved through solving an algebraic Riccati equation. A high gain observer is employed to obtain the estimation of states and then output feedback controller is constructed. Finally a simulation example is given to illustrate the performance of the proposed method.
