A novel chaotic system called complex Rikitake system is proposed. Dynamical properties, including symmetry, dissipation, stability of equilibria, Lyapunov exponents and bifurcation, are analyzed on the basis of theoretical analysis and numerical simulation. Further, based on feedback control method, the complex Rikitake system can be controlled to any equilibrium points. Additionally, this paper not only proves the existence of two types of synchronization schemes in the complex Rikitake system but also designs adaptive controllers to realize them. The proposed results are verified by numerical simulations.
提出了一种名为复利木系统的新型混沌系统。基于理论分析和数值模拟,分析了其动力学特性,包括对称性、耗散性、平衡点稳定性、李雅普诺夫指数和分岔。此外,基于反馈控制方法,可将复利木系统控制到任意平衡点。此外,本文不仅证明了复利木系统中两种同步方案的存在性,还设计了自适应控制器来实现它们。通过数值模拟验证了所提出的结果。
