摘要
讨论一类非线性动态系统的混合H2/H∞模糊输出反馈跟踪控制问题。首先利用T-S模糊模型对系统进行建模,然后设计基于观测器的控制器,使跟踪误差尽可能的小,并且对于任何有界参考输入,满足给定的H∞跟踪性能,以及在满足给定的H∞跟踪性能下,达到H2次优控制性能,最后将观测器与控制器的设计问题转化为EVP(特征值问题)。
The problem of mixed H2/H∞ fuzzy output feedback tracking control for nonlinear dynamic systems is studied in this paper. First the T-S fuzzy model is employed to represent the systems. Next, a fuzzy observer-based controller is developed to reduce tracking error as possible and guarantee a desired H∞ tracking performance for all bounded reference inputs, and achieve the sub-optimal H2 control performance with the desired H∞ tracking performance. Finally the problem of designing the observer and controller is translated into EVP（Eigenvalue Problem）.
