摘　　要：通过联碱碳酸化塔中与CO2浓度相关且可在线实时检测的参数，如进气量、温度、压力等，构造出CO2浓度的多元一次回归模型。并根据自适应辩识原理，对变量形式进行变换，导出可变窗口自适应辩识方法，建立了联碱碳酸化塔中CO2浓度估计器。利用该估计器的模型参数和可在线实时检测的相关参数，以及在线估计算法，使得联碱碳酸化塔中CO2浓度在线检测成为可能。The one-order-regress mode with multi-variables for the CO2 concentration is built according as the correlated online parameters such as the volume of the entering gas, the temperature and the pressure of the tower, etc. According to the principle of adaptive identification, the variable format is transform and the method of adaptive identification in variable window is derived, and an estimator for the CO2 concentration is developed. By using the model parameters of estimator and the correlated parameters and estimate algorithm for online detection online, the online detection of CO2 concentration in the tower can be realized.
