用两种方法来控制在连续流动釜式反应器(CSTR)中的Belousov-Zhabotinsky(BZ)化学混沌反应:(1)自适应延迟时间反馈控制方案;(2)线性自相互作用控制方案。第一种控制方案是一种微扰控制,并能将BZ-CSTR化学混沌稳定控制到其内嵌的不稳定周期轨道(UPO)上去。这种方法的优越之外可以由系统延迟时间的自适应调节得以显示。第二种控制方案可以驱动BZ-CSTR混沌动力学到达一系列规则的动力学状态,这些动力学状态可能并不是混沌轨道中内嵌的本征轨道。在控制BZ-CSTR化学混沌反应的实验中,这两种方案显示出了很大的灵活性和有效性。

The chaotic dynamics of Belousov-Zhabotinsky chemical reaction in continuous flow stirred tank reactor (CSTR) is controlled by two methods: (1)a self-adaptive delay feedback control scheme; (2)a linear self-interacting control method. The first control method is a kind of perturbation control and can stabilize the BZ-CSTR chemical chaos to its embedded unstable periodic orbits (UPO). The advantage of the method is illustrated by the self-adaptive regulation of the system delay time. The second control method can drive the BZ-CSTR chaotic dynamics to a new status of dynamics which may not be the original embedded intrinsic orbits of the chaos. Both methods illustrate great flexibility and effectiveness in controlling BZ-CSTR chemical chaos.
