摘　　要：介绍了一种改进的四阶蔡氏电路。首先采用理论分析的方法建立了电路的数学模型,然后分别采用数值和模拟两种方法对改进后的电路进行了仿真,得到了混沌现象,最后采用响应-驱动法实现了改进型电路的混沌同步。结果表明:改进型蔡氏电路产生了较原蔡氏电路更为复杂的混沌现象,更适合用于混沌通讯。In this paper, an improved fourth-order Chua＇s circuit is proposed. First, the mathematical model of the new circuit is established by theoretical analysis. Then, numerical simulation and theoretical analysis are re- spectively conducted for studying the nonlinear property of the circuit. Finally, chaos synchronization of the im- proved circuits verified through the response-driven approach. The results reveal that the new Chua＇ s circuit could produce more complex chaotic phenomena and more suitable for chaotic communications.
