The object of control is to lead the chaotic system into a stable state. Owing to these characteristics of chaotic motion, different controllers were designed to dominate the chaotic system in the control fields. First of all, the fuzzy system was represented by the Takagi-Sugeno (T-S) fuzzy model; then the linear matrix inequalities (LMI) were adopted to obtain the feasible feedback gains. An then, the idea of Parallel Distributed Compensation was adopted in the design of the stable fuzzy controllers. In this thesis, various constrains are adopted to design fuzzy logic controllers. These constrain includes stability, relaxed stability, decay rate, and decay rate with relaxed stability, and so on. Furthermore, the controlling results of the chaos system with these controllers are presented in this paper.
