苎麻纤维回潮率测试的灰色优化模型及误差分析

The Grey Optimum Model of Testing Moisture Regain of the Ramie Fabric and Its Error Analysis

利用Matlab工具通过优化设计计算,建立了不同优化方案的苎麻纤维回潮率快速测定的灰色优化GM(1,2)模型。同时,对不同方案的模型作对比分析并给出了最佳优化模型。在利用电阻测湿仪快速测定苎麻纤维水分时,可方便准确地计算出真值。

The accuracy of GM(1,2) model established in the light of the regular method was lower and its fitting error was bigger. Based on it, it was put forward that the object function was established with the aim of the least absolute value of the fitting error, it was calculated through the optimum design applying the Matlab, and the Grey optimum GM(1,2) model that was applied to quickly determining the moisture regain of the ramie fabric in different optimum schemes was established. At the same time, aiming at the fitting error, the best optimum model was given through the contrast analysis of model in varying optimum schemes The model could be conveniently applied to working out the real value when the moisture of the ramie fabric was quickly determined with a resistant -measuring instrument.
