摘要
为了解决延迟反馈控制中参数难以选取的问题,将混沌优化和模糊控制的方法应用到混沌系统的延迟反馈控制中,采用混沌优化方法确定出延迟反馈控制的延迟时间,利用模糊控制技术确定出控制刚度等参数,从而得到延迟反馈控制方法的参数.同时,利用本文算法,可以一次确定出混沌系统的多个不稳定周期轨道的周期.仿真结果验证了本文算法的有效性.
Chaos optimization and fuzzy control were applied in chaos control by time-delayed feedback method.Chaos (optimization) could find the proper delay time and fuzzy control could determine the control amplitude,which resolved the (problem) that the parameters in chaos control by time-delayed feedback method were difficult to be determined.Furthermore,the proposed method can also find several periods of unstable periodic orbits (UPO-s) in one search.The experimental results show that the proposed method is effective.
