摘要: 讨论了一类能用模糊动态系统模型表示的非线性系统的H∞输出反馈控制的设计. 分别基于一个共同的李亚普诺夫方程和一个分段微分的李亚普诺夫方程,给出了两种H∞ 输出反馈模糊控制的新设计方法.通过解一组线性矩阵不等式,可以得到H∞输出反馈控 制器.最后,举例说明了这两种新的设计方法.Abstract: This paper presents H∞ output feedback control design of complex nonlinear systems which can be represented by a fuzzy dynamic model. Based on a common Lyapunov function and a piecewise differentiable Lyapunov function respectively, two kinds of new H∞ output feedback fuzzy control design methods are developed. The H∞ output feedback controller can be obtained by solving a set of suitable linear matrix inequalities. An example is given to demonstrate the application of the proposed design methods.
