- 摘要:
- 提出利用2个具有滞环输出的CNN细胞实现了多涡卷混沌发生器.首先用标准CNN细胞的状态方程来表示多涡卷混沌发生器的状态方程，通过对比来确定CNN模板的参数，用运算放大器来实现CNN细胞的状态方程及不同形式的滞环输出方程，分别采用不同形式的滞环输出函数实现双涡卷和三涡卷混沌吸引子.本系统由运算放大器，电阻及电容构成，易于实现集成.最后，应用Orcad Pspice进行了电路仿真，验证了结论的正确性.
- Abstract:
- A realization of multiscroll chaos generation is presented using two CNN cells with hysteresis output function in the paper. First, the CNN template can be ascertained through expressing the unstable secondorder linear continuo u s system with the state function of CNN; Second, the state function of CNN and t he hysteresis output function are realized with operational amplifier; Finally, double scroll and three scroll chaos attractor are realized using different hyst eresis functions. The proposed system uses only operational amplifiers, resisto rs and capacitors, so it’s easy to be integrated. The results’ validity is ill ustrated by the circuit simulation using Orcad Pspice.
