摘要
按后序参数列 ,反向估计其相关前序参数的思路 ,应用可变窗技术 ,实施自适应滤波辩识 ,构造了纯碱生产碳酸化塔中 CO2 浓度的估计器 ,解决了在碳酸化过程中不能在线检测碳酸化塔中 CO2 浓度的问题 ,这对碳酸化过程的有效控制、CO2 浓度测量成本的降低与推进软测量技术有积极意义 .
Accoring to the train of thought of backward variable sets estimate it in front variable, using the variable window technology and the method of adaptive identifying, in the estimator of CO\-2 concentration carbonation tower can be formed, so that CO\-2 concentration in tower can be estimated online, which can provide useful information to process control and the cost for measuring the parameter can be saved.
