基于适应策略差分进化算法的化工反应动力学参数估值
Differential evolution using adaptive strategy for parameter estimation of chemical reaction kinetics
摘要
Abstract
To better predict the percentage of mercury oxidized based on the concentrations of other flue gas components,an accurate kinetic model for Hg oxidation needs to be developed. The existing models always contain some unknown parameters that are difficult to identify. To extract these parameters exactly and fast,this paper puts forward an adaptive strategy based on differential evolution (ASDE). The new ASDE contains candidate set for mutation strategy,scale factor(F)and crossover rate(CR). Each value in every candidate set has its own selection probability and the selection probability is updated according to the previous search information. Based on the selection probability, an adaptive model is designed to set the most proper control parameters for every vector in the main population. The ASDE is applied to solve parameter estimation problem of Hg oxidation models. The experimental results showed that ASDE is able to obtain more accurate model than other 6 algorithms. It is an effective approach for parameter estimation of chemical reaction kinetics.关键词
