Abstract
The application of polynomial regression in the smart sensor nonlinearity compensation was introduced by making use of least-squares polynomial regression analysis. The two kinds of compensation method were put forward. One is the quantity to be measured as the independent variable of fitting polynomial; the other is the sensor's response as the independent variable of fitting polynomial. Two kinds of compensation method is analyzed and contrasted by a practical example.
