研究具有外部不确定性Rssler混沌系统的鲁棒跟踪控制问题.基于动态面控制原理设计自适应鲁棒控制器,给出了系统参数的自适应更新律,使得被控闭环系统的各误差变量一致有界.系统输出曲线渐近跟踪任意期望轨道,且跟踪误差能被控制在任意小的范围内,而无须知道系统的参数及外部不确定性的界限.基于稳定理论给出了具体的稳定性分析,并通过数值仿真验证了该方法的有效性及鲁棒性.
The robust tracking control problem of Rssler chaotic system with external uncertainties is studied.An adaptive robust controller is designed based on the principle of dynamic surface control and an adaptive renewal law of the system parameters is given to make the error of the controlled closed-loop system The variables are uniformly bounded.The system output curve asymptotically tracks any desired orbit, and the tracking error can be controlled in any small range, without having to know the limits of the system parameters and external uncertainty.Based on the stability theory, given the specific Stability analysis, and verify the effectiveness and robustness of the method through numerical simulation.
