阐述了不确定混沌系统降阶反同步的概念。基于参数调制和自适应控制技术，我们证明了即使参数未知，三阶混沌系统的动力学演化也可以与四阶混沌系统的投影反同步。将该方法成功地应用于超混沌Chen系统（四阶）和Lü系统（三阶），理论分析和数值仿真验证了结果.
In this present paper, we elaborated the concept of the reduced-order anti-synchronization of uncertain chaotic systems. Based upon the parameters modulation and the adaptive control techniques, we show that dynamical evolution of third order chaotic system can be anti-synchronized with the projection of a fourth-order chaotic system even though their parameters are unknown. The techniques are successfully applied to several examples: hyperchaotic Chen system (fourth-order) and Lü system (third-order), theoretical analysis and numerical simulations are shown to verify the results.
