摘要
针对模拟电路混沌系统实现易受外界条件影响等不足,本文提出了一种基于LabVIEW实现微弱信号混沌检测系统的方法。利用强大的数值计算软件LabVIEW求解Duffing方程,通过识别系统输出的相轨迹的变化检测估计微弱信号。实验结果表明,利用LabVIEW产生的实验结果与理论仿真结果一致,证实了基于LabVIEW的微弱信号混沌检测方法是可行的,这为混沌系统的数字实现提供了新的思路。
In order to overcome the effects caused by external conditions in the analog circuit＇s chaotic system, a method of weak signal chaotic detection based on LabVIEW was proposed. Dulling equation was solved by the powerful numerical calculation software LabVIEW. The weak signal was detected and estimated by the phase trajectory change of recognition system output. Experimental results by LabVIEW were consistent with the theoretical simulation results by Matlab. This method proved a new and effective way for the realization of the chaotic system.
