摘要/Abstract

摘要： 将主动backstepping控制方法应用于2个不同的混沌系统并实现投影同步，通过不断递推，选取一系列Lyapunov函数来设计控制器，使误差系统快速稳定在平衡点.最后以Lorenz系统和Chen's系统为例，进行了数值模拟.

关键词: 比例因子, 投影同步, 主动backstepping控制

Abstract: An effective active backstepping method is applied to projective synchronization of two different chaotic systems. The proposed scheme offers a recursive procedure where active control is designed by selecting a series of Lyapunov functions to quickly stabilize the error system at equilibrium. Numerical simulations for projective synchronization of the Lorenz system and Chen's system demonstrate effectiveness of the method.

Key words: projective synchronization, scaling factor, active backstepping control
