| 摘 要： | 针对如何准确测定混合染液染料浓度，尤其当混合染液浓度太大时由于染料自身发生如水解等化学变化以及染料之间的相互作用，其吸光度体系呈非线性的情况，提出了通过建立非线性吸光度模型，并利用粒子滤波算法同时测定混合染液中各染料浓度的解决方法。以3种活性染料的混合染液为例,对该方法的可行性进行验证，并与扩展卡尔曼滤波算法进行滤波效果对比。实例证明,非线性吸光度模型是准确的，基于粒子滤波算法的测定方法是有效可行的。

| Abstract: | For the determination of individual dye concentrations in the mixture,especially in the case that the concentration of the mixture is too high and the absorbance system is to be nonlinear because of chemical changes such as hydrolysis and the interaction among the dyes,a novel determination method based on particle filter is proposed and a nonlinear absorbance model is developed.The feasibility and validity of this method can be verified by real examples.The numerical results for the determination of individual dye concentrations in the mixed reactive dye liquors by particle filter are compared to the results of the determination method based on extended Kalman filter,showing that the particle filter can produce better filtering effect than extended Kalman filter and the mean squared error(MSE)between its determinated results and actual values is less than 0.015.This demonstrates that the nonlinear absorbance model developed in this paper is accurate and the determination method based on particle filter is effective and feasible. |
