Abstract
Due to the output of the sensor is sensitive to temperature change
the inverse model of sensor system for temperature compensation is built based on support vector machine(SVM).Examples of analysis show that compared with the method of RBF neural network compensation
SVM inverse model improves the linearity of the sensor and the compensation curve is smoother
