摘　　要：提出了一种基于第二代电流控制电流传输器(CCCII)实现多涡卷混沌吸引子的方法.首先,分析了Jerk双涡卷混沌系统的基本动力学特性;其次,在双涡卷Jerk混沌电路的基础上,构建了基于CCCII的阶跃函数序列电路,并利用此非线性函数电路来扩展双涡卷Jerk混沌电路的指标2的鞍焦平衡点,设计了多方向的多涡卷混沌电路,而且设计的混沌电路能在高速高频环境中应用;最后,通过硬件电路实验验证了该方法的可行性.In this paper,we propose a new method of generating multi-scroll chaotic attractors base on CCCII.Firstly,some basic dynamical properties of Jerk double-scroll chaotic system are studied.Furthermore,we construct the SNFS with CCCII and design the multi-scroll chaotic system by using this circuit based on the double scroll chaotic Jerk circuit.By analyzing the characteristics of CCCII we could learn that the circuit can work in a higher frequency range and the structure of the circuit is simple.Finally,the effectiveness of this method is verified by the Pspice simulation results of the circuit.
