蔡氏电路数值仿真图像与实测图像的对比研究

A Comparative Study Between CAI's Circuit Simulation Image and Measured Image

三阶自治电路—蔡氏电路在特定的条件下可以产生混沌现象。本文基于MATLAB软件对建立的电路模型进行了数值仿真,并将结果与真实实验测得的图像进行了对比分析。结果表明,蔡氏电路的数值仿真图像与实测图像基本吻合;而基于MATLAB的数值仿真能够更精确的调节模型参数,更清晰地表现混沌现象的行为变化。

The third order autonomous electrical circuit-Chua’s circuit can produce chaos under certain conditions.We make the numerical simulation of the established circuit model based on MATLAB and compare its images with the measured images obtained from the real experiment.The results show that the numerical simulation results are in good agreement with the measured images;more over the numerical simulation can adjust the model parameters more accurately and show the behavior change of chaotic phenomena more clearly.
