本文研究了中、小氮肥厂合成氨生产中氢氨比控制问题,文中给出了系统模型,对未知模型参数进行实时辨识,利用中间变量构成最佳线性预估器,采用自校正控制方案,并在系统中引入专家系统方法,实现了氢氨比控制。
In this paper, we study the control of hydrogen and ammonia ratio in the production of ammonia in medium and small nitrogenous fertilizer plants. The system model is given in this paper. The unknown model parameters are identified in real time. The intermediate variables are used to construct the optimal linear predictive controller. Introduced in the system expert system approach to achieve the hydrogen-ammonia ratio control.
