摘要
本文通过控制有源积分三角波振荡器的逻辑部件和充放电关系,使其产生混沌振荡。在初值不变情况下, 利用混沌系统对参数的极度敏感特性,提出了一种非线性测量积分电容的方法。论证了这种混沌振子所产生的动力 系统是一种倒的锯齿映射,并给出了电容的计算公式,实验结果也证明了这种测量方法的有效性。
By controlling its logic unit and relationship of charge and discharge, the active integrating triangle-wave oscillator is forced to generate chaotic oscillating. A nonlinear method of capacitor measurement is proposed because chaotic systems have the properties of extremely high sensitivity to parameters in constant initial conditions. Theoretical analysis shows the dynamic system in the chaotic oscillator is an upside-down saw-tooth mapping system, the capacitor calculation formula is given. Experimental results have proven the feasibility of this measuring method.
