摘　　要：应用控制理论推导了异结构混沌系统产生广义投影同步的条件;研究表明当驱动系统和响应系统出现同步时,2个系统的响应误差极限为0,同时投影同步时响应系统产生的混沌吸引子可以以α比例因子缩放。通过对Lorenz系统和Chen’s系统的数值仿真证明了控制器设计的可靠性。A sufficient condition is attained for the stability of the error dynamics between two different chaotic system projective synchronization by applying control theory, Research suggests that the limit of response error between driver system and response system is zero when synchronization occur, meanwhile, the chaotic attractor of response system can magnify and deflate according to scaling factor when projective synchronization happen. Finally we take Lorenz system and Chen＇ s system as an example for illustration and verification.
