摘要:
为了克服模拟电路混沌系统设计易受外界条件影响，提出了一种基于DSP Builder设计混沌吸引子的方法。以整数阶Jerk混沌系统为例，采用一阶数字差分算法使混沌系统离散化，利用Matlab/Simulink中的DSP Builder工具箱设计了一个混沌电路模型。仿真结果表明，DSP Builder下与Matlab下仿真结果基本一致，这为混沌系统的数字化设计提供了新的思路。
Abstract:
To solve the problem that the chaotic system of analog circuit system is vulnerable to external conditions,a method of designing a chaotic attractor based on DSP Builder is proposed.Taking the Jerk chaotic system as an example,the chaotic system is discretized by a difference method of first order and built by DSP Builder which is embedded into the Matlab/Simulink as a toolbox.The simulation results show that the conclusion in the DSP Builder software and the conclusion in the Matlab software are basically consistent,providing a new way for the design of chaotic system.
