三阶蔡氏电路变阻器阈值的数值估计

Numerical Estimation of Rheostat Threshold in 3-dimension Chua's Circuit

从理论分析和仿真实验两个角度分别研究三阶蔡氏电路的不同运行状态.研究中以变阻器阻值为控制参数,通过Matlab数值计算,模拟电路的运行状态.具体将蔡氏电路的状态归纳为稳定态、周期态、混沌态和负阻尼振荡态.根据数值计算结果得出可变电阻的安全阈值,为硬件实验提供参考.

The circulated state of 3dimension chua's circuit which the value of rheostat is regarded as control parameter are simulated by Matlab numerical computer and theoretical in the paper. The circulated state of chua's circuit are concluded as steady state, periodic state, chaotic state and negative damping oscillated state.Based on numerical computer results security threshold of rheostat in chua's circuit is acquired, provided with the reference for experiment.
