摘要: |
将开关控制信号直接输入到被控的混沌系统中,仅通过改变外部脉冲开关信号的幅度、极性、宽度等参数,实现蔡氏混沌系统的各种不稳定周期轨道的稳定控制.在此控制策略基础上,引入变量反馈与脉冲开关来共同调制系统参数,研究变量反馈参数开关的调制控制.数值模拟和电路仿真的结果表明,混沌系统的变量反馈参数开关的调制控制方法能有效地把混沌电路系统控制到系统的左右不动点和np周期轨道.该方法对其他混沌电路的参数控制有一定的参考价值. |

Abstract: |
The method of parameter switching modulation with variables feedback for control chaotic system on the basis of the methods without variables feedback is studied.The chaotic Chua's circuit is selected as a typical example,and is controled by using switching modulation with variables feedback on one of it's capacitor parameters.The chaotic circuit can be controlled to it's fixed point as well as np periodical orbits.The experimental results and numerical simulation have demonstrated that this chaos control method is effective,which has certain valuable reference for realizing chaotic circuits control in engineering. |
