运用传感器的静态标定值,拟合信号调理器的传输函数,使由传感器和信号调理器共同组成的传感器通道的传输函数为线性函数。针对这种情况,论述并证明了用全最小二乘法比用最小二乘法能获得更高的拟合精度。
The static calibration value of the sensor is used to fit the transfer function of the signal conditioner so that the transfer function of the sensor channel composed of the sensor and the signal conditioner is a linear function. In view of this situation, it is demonstrated and proved that the least squares method can obtain a higher fitting accuracy than the least squares method.
