模糊遺傳算法在混沌控制中的應用

Application of a time-delayed feedback control method based on the fuzzy genetic algorithm for chaos control

摘要: 將模糊遺傳算法與混沌的延遲反饋控制方法相結合,提出了基于模糊遺傳算法的延遲反饋控制方法.它利用模糊遺傳算法強大的尋優能力來整定延遲反饋控制中的控制剛度矩陣參數,從而克服了延遲反饋控制中控制剛度難于確定的問題.對混沌Lorenz系統的仿真控制說明該算法具有快速性好和抗干擾能力強等優點.

Abstract: A time-delayed feedback control method based on the fuzzy genetic algorithm was proposed for chaos control. The fuzzy genetic algorithm was used to optimize parameters of the time-delayed feedback control method. The results of simulation for controlling a chaotic Lorenz system to a fixed point and a period-2 orbit show that the new algorithm has many advantages such as fastness and strong anti-interference.
