铜阳极恒电位电流混沌的延时反馈控制

Time delay feedback control over potentionsatiocl current chaos of copper anode

用延时反馈控制方法实现了对铜阳极恒电位电流混沌周期 -1 ,周期 -2 ,周期 -3 ,周期 -4的控制。被稳定的周期 -1 ,2轨道与原系统的周期 -1 ,2轨道相同 ,而被稳定的周期 -3 ,4轨道却与原系统的不同。控制到周期 -1的控制权值 K的合适范围是 [0 .0 4,0 .2 ],控制到周期 2 ,3 ,4的 K值的合适范围为 [0 .0 2 ,0 .1 ]。

The period-1, period-2, period-3, and period-4 control over potentiostatical current chaos of copper anode in Cu-H 3PO 4 system is achieved by time delay feedback control. The period-1, period-2 orbits that are controlled are the same of the original orbits ,and the period-3, period-4 orbits that are controlled are not the same of the original orbits. The proper arrange of control weight is from 0.04 to 0.2 when the period-1 control is achieved, and the proper weight arrange is from 0.02 to 0.1 when the period-2, period-3 and period-4 controls is achieved.
