摘要
采用主动控制法和非线性控制法实现了超混沌Chen系统和超混沌Qi系统的不同结构间的反同步,设计了不同的控制器,使得两个超混沌系统实现异构反同步.基于线性系统稳定性原理,运用主动控制法来判别误差动态系统的稳定性;通过构造Lyapunov函数,运用了非线性控制法使两个超混沌系统得以反同步.数字仿真模拟验证了方法的有效性和可行性.
Anti-synchronization between hyperchaotic Chen system and hyperchaotic Qi system with different structure is investigated by using active control method and nonlinear controller. Two different controllers are designed for anti-synchronizing these two different hyperchaotic systems. Based on linear system stability theory, the active control synchronization method is used to determine the stability of error dynamical system. The two hyperchaotic systems can be anti-synchronized by constructing Lyapunov function via nonlinear control method. Numerical simulation shows the effectiveness and feasibility of these two methods.
