摘要
研究了复杂非线性系统(如混沌非线性系统)的稳定控制问题。采用T-S模糊动态模型描述非线性系统,并将非线性系统模糊化为局部线性模型。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系统变结构控制相结合,来解决非线性系统控制问题。应用到两类混沌系统的稳定控制中,验证了方案的有效性。
The problem of stable control for complex nonlinear system such as chaotic nonlinear system is studied. Nonlinear system is described based on T-S fuzzy dynamical model, and the nonlinear system is translated into local linear model by fuzzy method. The variable structure controller insuring the 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 validity of the scheme is tested by controlling two kinds of chaotic systems.
