摘要
介绍了模拟退火算法的基本原理,阐述了该算法拟合曲线的一般步骤。针对JJG 229-2010《工业铂、铜热电阻检定规程》,在最小二乘法的基础上,利用模拟退火算法拟合铂电阻的热特性曲线,分析了这一算法在拟合过程中的稳定性。结果表明:模拟退火优化算法同样适用于曲线拟合过程,拟合过程的稳定性有待进一步研究。
The basic principle of the simulated annealing algorithm, described the general steps of the algorithm curve fitting. On the basis of JJG 229-2010＂Verification Regulation of Industry Platinum Copper Resistance Thermometers＂ and the least squares method, using simulated annealing algorithm to fit platinum resistance characteristic curve analysis of the stability of this algorithm in the fitting process. The results showed that： simulated annealing optimization algorithm is equally applicable to the curve fitting process, the stability of the fitting process for further study.
