介绍了带材边界位置测量传感器的原理,并根据传感器的输入-输出特性,提出用最佳一次逼近多项式或近似最佳三次逼近多项式逼近输出函数,从而方便地计算出带材边界的位置。
The principle of strip boundary position measuring sensor is introduced. According to the input - output characteristic of the sensor, an optimal one - time approximation polynomial or approximate best three times approximation polynomial approximation output function is proposed to calculate the position of the strip boundary conveniently.
