摘要:
针对 GMM-FBG 电流传感器中超磁致伸缩材料引起的磁滞非线性问题,提出一种基于图形学规律的校正方法。通过分析已知迴线的图形学规律,来预测未知输入电流对应迴线的数学模型,
并用它的逆模型对传感器输出的电压信号进行磁滞非线性校正求出输入电流信号,最后实验表明这种校正方法能准确重建输入电流信号。与未校正时比较发现,测量范围内瞬时误差及幅度误差降低。
Abstract:
Aiming at the problem of hysteresis nonlinearity caused by gaint magnetostrictive material inGMM-FBG current sensor,a kind of hysteresis nonlinear correction method based on graphics law is pro-posed. Through analysis of the graphics law of these known hysteresis loops,which was adopted to predictthe unknown input current corresponding to the hysteresis loop mathematical model,and by using the in-verse model to correct the hysteresis nonlinearity of voltage signal which was obtained by the sensor,thesignal of the input current was obtained. Finally,the experiment shows that the input current signal canbe reconstructed accurately with the correction method. Comparing with non-correction,the instantaneouserror and amplitude error can be reduced in the measurement range.
