双曲型混沌电路及其Multisim仿真
Electronic circuits manifesting hyperbolic chaos and their simulation with software package Multisim
摘要:
我们考虑几个电子电路,这代表动力系统的双曲型混沌吸引子的Smale-威廉姆斯型,并证明其模拟使用的软件包NI Multisim 10的结果。所开发的方法是有用的,作为一个中间步骤,构建真正的电子设备表现出结构稳定的双曲混沌适用于例如在系统的安全通信,噪声雷达,加密系统和随机数发生器。这也是方法论的兴趣,培养学生谁专门从事无线电物理学和非线性动力学的设计和分析系统与复杂的动态使用的例子接近实际应用。
英文摘要:
We consider several electronic circuits, which represent dynamical systems with hyperbolic chaotic attractors of Smale-Williams type, and demonstrate results of their simulation using the software package NI Multisim 10. The developed approach is useful as an intermediate step of constructing real electronic devices manifesting structurally stable hyperbolic chaos applicable e.g. in systems of secure communication, noise radar, for cryptographic systems and random number generators. This is also of methodological interest for training students who specialize in radio-physics and nonlinear dynamics in the design and analysis of systems with complex dynamics using examples close to practical applications.
