设计了参数观测器,对Feng混沌系统中未知参数进行识别。采用反步控制方法,在存在输入扰动项的情况下,构造模糊自适应控制器控制Feng混沌系统。模糊逻辑系统用来逼近反步控制方法中出现的未知、非线性且结构复杂的函数。和传统的反步控制方法相比,本文采用的控制器结构简单,易于实现。仿真的结果验证了本文控制方法的有效性。 A parameter observer is designed to identify unknown parameters in Feng chaotic system. Using backstepping control method, fuzzy chaotic system is constructed by fuzzy adaptive controller in the presence of input disturbance term. Fuzzy logic systems are used to approximate unknown, nonlinear, and complex functions that occur in backstepping control methods. Compared with the traditional backstepping control method, the controller used in this paper is simple and easy to implement. The simulation results verify the effectiveness of the proposed control method.
