| 摘 要： | 为了实现一类新型混沌系统的同步控制,提出一种基于T-S模型的模糊控制方法。利用T-S模糊模型对Nadolschi混沌系统进行精确描述;采用并行分布补偿技术设计状态反馈控制器;进而将Nadolschi系统的同步控制问题转化为误差模糊系统零平衡点的镇定问题。然后,利用精确线性化的方法将误差模糊系统转换成定常系统,最后,根据线性系统理论,得出使Nadolschi混沌系统达到渐近同步的充分条件。仿真结果验证了所提方法的有效性,所设计的模糊控制器具用结构简单,规则少,控制响应速度快等优点。

| Abstract: | A fuzzy control method was developed to synchronize a class of chaotic systems with T-S fuzzy models were used to model the chaotic systems.The parallel distributed compensation technique was used to design a state feedback controller for the chaotic systems.Then,the synchronization of the chaotic systems is converted into the stabilization of fuzzy error systems at the equilibrium point.Exact linearization is used to transform the fuzzy error systems into timeinvariant systems.The sufficient condition for synchronization of the Nadolschi chaotic systems is derived based on linear systems theory.Simulation results demonstrate the effectiveness and speed of the method.The controller is simple and needs few fuzzy rules. |
