| 摘 要： | 利用电子线路实验实现了用变量脉冲扰动法控制离散混沌 .该方法只用单一输出信号作为反馈信号 ,每隔一定的脉冲间隔将其加到系统的某些变量中去 ,适当调节脉冲间隔和反馈系数 ,可得到多个稳定的周期轨道 .该方法不仅适用于一维和二维离散系统 ,也适用于三维或更高维的离散系统 .

| Abstract: | The control of discrete chaos in the circuit with the method of pulse disturbance to system variables is realized. By means of a single feedback output signal of the system, which is added to some variables of the system per definite pulse intervals, a various of stable periodic orbits are obtained by properly adjusting pulse intervals and feedback coefficient. This method is not only suitable to one or two dimensional discrete systems but also to three or higher dimensional ones. |
