摘要

摘要: 該文針對含未知參數的異結構超混沌復系統(tǒng)，基于自適應控制及Lyapunov穩(wěn)定性理論，提出一種新的自適應廣義組合復同步方法 (GCCS)。首先給出廣義組合復同步的定義，將驅動-響應系統(tǒng)的同步問題轉化為誤差系統(tǒng)零解的穩(wěn)定性問題；然后從理論上設計了非線性反饋同步控制器及參數辨識更新律，并引入誤差反饋增益，以控制同步的收斂速度；最后以超混沌復Lorenz系統(tǒng)、超混沌復Chen系統(tǒng)、超混沌復L系統(tǒng)的廣義組合復同步與參數估計為例，從數值仿真角度驗證了所提方法的正確性和有效性。

Abstract: Based on adaptive control and Lyapunov stability theory, a novel adaptive Generalized Combination Complex Synchronization (GCCS) scheme is proposed for nonidentical hyperchaotic complex systems with unknown parameters. Firstly, the definition of GCCS is presented, and synchronization of drive-response systems is transformed to the zero solution analysis of the error dynamical system. Secondly, a nonlinear feedback controller and parameter update laws are theoretically designed, wherein error feedback gains are introduced to control synchronization speed. Finally, GCCS among the hyperchaotic complex Lorenz system, complex Chen system, and complex L system is carried out to verify the correctness and effectiveness of the proposed scheme by numerical simulation.
