摘要
针对光纤电压传感器中的温度补偿问题,利用MATLAB软件,采用最小二乘多项式拟合法,对平均偏差值进行四阶多项式拟合,建立补偿方程。通过补偿方程找出温度影响因子,从而对系统进行温度补偿。经过数据处理,最大误差由补偿前的11.84%降低到补偿后的0.24%。
In the view of the temperature compensating for fiber optic voltage sensor, uses MATLAB software and the method of least squares polynomial fitting to carry on four steps polynomial fitting for the output deviation of mean value and establish compensating equation. According to the compensating equation and the temperature influence factor temperature compensation to the system is carried on. After the data processing the maximal error of the measuring result is reduced from 11.84% before the compensating to 0.24% after the compensating.
