摘　　要：采用CARMA模型对单集气管阀位和压力的关系进行建模,通过寻找具有较大信息熵的模型准则来决定模型阶次,取实际值与计算值误差的平方和达到最小为目标函数进行参数估计,实现对集气管模型的辨识。预测压力和实际压力的比较结果证实了CARMA模型在集气管压力控制中的有效性。CARMA is adopted for modeling the relationship between the valve location and pressure of single gas collecting main. Model order can be determined by adopting modeling principle with large information entropy. Parameter estimation is carried out taking minimizing the quadratic sum of deviation values actual value and calculated value as objective function, so as to identify the model of gas collecting main. The comparison result between predicted pressure and actual pressure proves the effectiveness of CARMA in the control of gas collecting main pressure.
