摘要
为了解决具有时滞的混沌系统的同步问题,提出了基于T-S模糊模型的H∞控制方法,通过求解LMIs的可行解从而获得系统控制器的增益和公共正定矩阵,实现两个模糊时滞混沌系统的同步。设计的模糊误差控制器结构简单,且该方法适用于绝大多数时滞混沌系统的同步控制。仿真表明了方法的有效性。
The problem of synchronization for time-delay chaotic systems was solved via H∞ control method based on T-S fuzzy models. LMIs-based design problems were defined and employed to find feedback gains of simple fuzzy controllers and common positive definite matrices realizing synchronization of fuzzy time-delay chaotic systems, which could be applicable to a large class of time-delay chaotic systems. Numerical simulation shows the effectiveness and feasibility of the proposed method.
