摘要
针对最新提出的统一混沌系统,给出了一种单参数采样数据反馈控制器.对α取不同值时的统一系统,以给定的频率采样输出作为控制信号,构造离散时间控制算法,以达到将统一混沌系统控制到平衡点的目的.通过大量数值试验,找出了不同α值的统一系统一致渐近稳定地控制到平衡点的控制参数取值范围,并且检验了该方法的鲁棒性.
Control for the unified chaotic system using sampled-data feedback control was proposed. For various values of the parameter α, the sampled output of the unified chaotic system at a given sampling rate was applied as the controlling signals. Then the sampled data were used to construct a discrete-time feedback control algorithm so that the unified system could be controlled to reach its equilibrium points. Through plenty of numerical experiments, for various values of the controlling parameter α, the ranges of α was gotten, for which the corresponding systems could be controlled to reach its equilibrium points with uniform asymptotic stability. Finally the robustness of this method was verified.
