Chinese Abstract

本文設計了一種連續狀態反饋(CSF)方法控制非線性混沌系統,並將此方法應用到混合光學雙穩(MOB)系統混沌的控制上,驗證其有效性。文中給出了CSF控制方法的構建依據、控制原理以及控制參數的選擇技巧並使用計算機數值模擬了MOB系統混沌被控制後的動力學行為。數值分析結果表明,適當地調整控制參數不僅可以實現原混沌系統內部的非穩定週期軌道穩定化,還可以將原混沌系統控制到其他的目標週期軌道上去。此種控制方法穩定性好,控制速度快,且可以方便靈活地獲得1p、2p、3P…2(上標 m)p×3(上標 n)p(m,n為整數)等多種穩定的週期軌道。同時,CSF方法對低週期和高週期軌道的控制都很有效。

English Abstract

A continuous state feedback (CSF) method is proposed to control nonlinear chaos system. Mixed-optical bistable (MOB) chaos system is taken as a typical example to demonstrate the effectiveness of this method. Construction foundation, control principle and control parameters' selections are presented. The dynamics behaviors of controlled MOB system are analyzed by computer numerical simulation using MATLAB programs. The control results indicate appropriately selecting control parameters not only can control the unstable periodic orbits embedded in initial system to stable periodic orbits, but can control chaos system to other desired periodic orbits. Control speed if CSF method is fast and stability is high, 1P, 2P, 3P…2(superscript m)P×3(superscript n)P(m, n are integers) various stable periodic orbits can be expediently obtained. This control method is effective on controlling low and high periodic orbits.
