延迟反馈对电光双稳态系统的混沌控制

Chaos Control of Electrical-Optical Bistable Systems by Delay Feedback

研究了系统参数变化对电光双稳态系统稳定性影响,针对由系统参数变化而引起的电光双稳态系统的混沌,提出了用延迟反馈的方法进行混沌控制,分别对系统参数和系统变量进行连续反馈控制。数值分析表明,系统参数变化会导致电光双稳态系统产生混沌。不论是对系统参数还是对系统变量进行反馈控制,只要反馈强度选择适当,都可以将系统的混沌态稳定到各个不同的周期轨道上。

This paper analyses the effect of the stability in electrical-optical bistable system. A delay feedback method which acts on different positions of the system is proposed to control the chaos gen-erated by parameter changes. The state evolvement of numerical simulations show that chaos can be generated by changed parameter, and the system can be all controlled to different stable periodic or-bits by choosing feedback intensity properly.
