摘 要: 应用反馈精确线性化方法给出了受控一类混沌系统的标准型,然后利用标准形将线性部分和非线性部分的分离特点进行了鲁棒控制器的设计,由此设计出原混沌系统的非线性鲁棒控制器,并证明其具有指数稳定性,仿真结果表明用反馈线性化方法设计的非线性鲁棒控制器的有效性. A standard model of a class of unified chaotic controlled systems is established by a method of feedback accurate linearization. Then the robust controller is designed by utilizing the separation characteristic of linearity and non-linearity of the standard model, thereout the nonlinear robust controller of the original chaotic systems, which is exponentially stable by proof, is obtained. Finally, the simulation results show the validity of the designed nonlinear robust controller by the method of nonlinear feedback linearization .
