摘要
研究了在有界干扰情况下一类非线性反馈混沌系统的鲁棒同步状态观测器设计问题。基于Sylvester矩阵方程的参数化解,将非线性反馈混沌系统的鲁棒同步状态观测器设计问题转化为带有约束条件的优化问题,通过解决该优化问题得到鲁棒同步状态观测器的增益矩阵,从而达到了干扰信号解耦目的。数值算例及其仿真结果表明:该非线性反馈混沌系统的鲁棒同步状态观测器的设计方法是简单有效的。
The robust state observer design problem of synchronization in a class of nonlinear feedback chaotic systems with a bounded disturbance is investigated in this paper.Based on the parametric solutions of a Sylvester matrix equation,the robust state observer design problem of synchronization in a class of nonlinear feedback chaotic systems is changed into an optimal problem with constraints.By solving the optimal problem,the gain matrix of the robust state observe of synchronization is obtained,which can make...
