摘要
针对Chua混沌系统这一复杂的非线性系统给出一种基于T-S模型的模糊变结构控制律设计。首先采用T-S模糊动态模型描述非线性系统,得到混沌系统的全局模糊模型;然后采用Lyapunov稳定性理论设计出确保模糊动态模型全局渐近稳定的变结构控制器,将模糊控制与成熟的线性变结构控制相结合,来解决非线性系统控制问题。仿真验证了方案的有效性。模糊控制器简单,规则少。
The design of fuzzy variable structure control law is presented for Chua chaotic system as a class of complex nonlinear system.The global fuzzy model is obtained by employing T-S fuzzy dynamical model.Then the variable structure controller insuring stability of global fuzzy dynamic system is designed by Lyapunov theory.The problem of controlling nonlinear system can be solved by combined fuzzy control with mature linear system variable structure control.The simulation results show the validity.The fuzzy controller is simple and need no much rules.
