NTC热敏电阻特性曲线的拟合方法研究
Study on curve fitting methods of NTC thermistor characteristics
摘要
Abstract
The temperature measurement accuracy is determined by thermistor characteristic equation. Three curve fitting methods of NTC thermistors and solutions methods of corresponding equations were introduced. An adaptive algorithm based on cross-validation for the powers of Chebyshev polynomials equation was proposed. It is shown that least squares for Steinhart-Hart equation and Chebyshev polynomials equation have great accuracy and the curve fitting equation determined by the adaptive algorithm for the Chebyshev polynomials method has better performance by experiment.关键词
