摘要
研究了混沌系统的同步问题。采用T-S模糊动态模型描述混沌系统,用Lyapunov稳定性理论设计出全局渐近稳定的模糊变结构同步控制器。应用到两Lorenz混沌系统的同步控制中,仿真验证了方案的有效性,模糊控制器结构简单,规则少,有实用价值。
The problem of chaos synchronization is studied. Chaos system is described by T-S fuzzy dynamical model. Fuzzy variable structure synchronization controller that insures the asymptotically stability of global T-S fuzzy model is designed based on Lyapunov theory. Being used in synchronization control of two Lorenz chaotic system, the effect of the scheme is tested by simulation. The Fuzzy controller is simple, and need little rules. It is worth being applied.
