| 摘 要： | 以跟踪误差渐进趋近于零为基础,提出了一种新的离散混沌系统延时反馈控制方法。该方法利用离散混沌系统的N步延时输出来估计系统的不稳定N周期轨道,并作为跟踪目标,使受控混沌系统既能稳定到相空间的确定点,又能稳定到N周期轨道。理论分析和实验均表明该控制方法具有鲁棒性。

| Abstract: | Based on the fact that the tracking error asymptotically approaches zero, a new nonlinear delayed feedback control approach of discrete chaotic systems is presented. Such control approach that uses the step-N delayed output of a chaotic system to estimate the unstable period-N orbit and to be the tracking target can stabilize a controlled chaotic system onto a deterministic point in the phase space as well as a period-N orbit. Theory and experiments show that the control approach is robust. |
