    Mechanism Modeling and Parameter Estimation of Conversion Rate in Methanol Synthesis Tower Based on Improved Wolf Pack Algorithm

    • 摘要: 以某甲醇合成塔为研究对象,通过深入分析甲醇合成过程的反应机理,建立了甲醇转化率软测量机理模型。为了提高模型参数的估计精度,提出了一种改进的狼群算法,引入了历史次优的概念与禁忌搜索机制。仿真实验结果表明,改进算法的全局搜索能力明显优于基本算法。以某甲醇合成过程的实际运行数据为样本,运用改进的狼群算法对甲醇转化率机理模型进行参数估计,与基本狼群算法相比,获得的参数精度更高,能更准确地预测合成塔出口处的甲醇转化率。

       

      Abstract: Aiming at the methanol synthesis column,this work establishes the soft sensor mechanism model of methanol conversion by analyzing the reaction mechanism of methanol synthesis.In order to improve the estimation precision of model parameters,an improved wolf pack algorithm is proposed,which integrates the concept of historical subprime and tabu search mechanism.Simulation results show that the improved algorithm has better global search ability than the basic algorithm.And then,by taking the actual running data of one methanol synthesis column as the sample,the model parameters of methanol conversion is estimated via the improved wolf pack algorithm.Compared with basic wolf pack algorithm,the improved algorithm can achieve higher accuracy and predict the methanol conversion exactly.
