| 摘 要： | 为缩短混沌电路的研究周期,提出了一种利用虚拟仪器实现混沌电路的方法。采用改进型欧拉算法对文氏桥混沌电路的状态方程进行近似处理,建立了相应的离散模型。在虚拟仪器(Labview)环境下进行数值仿真,可观察到在电路参数变化时电路动力学行为的演变过程,并通过构建采集系统,实现了文氏桥混沌电路离散模型的混沌信号输出。仿真结果与已有研究结果完全一致,有效地体现了"软件既是仪器"的概念。

| Abstract: | To shorten the research cycle of chaotic circuits,an approach to realize chaotic circuits is proposed by utilizing virtual instrument.By employing the improved Euler algorithm to approximately process the state equations of Wien-bridge chaotic circuit,the corresponding discrete model is established.With the variations of the circuit parameters,the dynamical evolutions of the circuit is observed numerically under the virtual instrument.Finally,by constructing an acquisition system,the chaotic signal output o... |
