摘　　要：选取了在电路上易于实现的两个异结构三阶自治混沌系统,并对其进行了混沌特征分析.运用EWB软件设计了实现2个混沌系统的实验电路.分析表明,两系统拓扑不等价,但奇异吸引子结构具有一定相似性.提出了一种非线性反馈控制方法实现两系统之间的混沌同步.数值仿真结果证明了理论分析的正确性.Two different structures of third-order autonomous chaotic systems which is easy to realize in electric circuit are chosen.The characteristics of the two chaotic systems are analyzed.Experimental circuits are designed about two chaotic systems using the simulation software EWB.Two systems are not topologically equivalent,but they have similarity in the strange attractor structure.Chaos synchronization between the two systems is realized via nonlinear feedback control.The nonlinear feedback controller is des...
