柠檬酸生产过程中溶解氧控制策略的研究

STUDY ON DISSOLVED OXYGEN CONTROL LAW IN THE PROCESS OF ACID

溶解氧是柠檬酸发酵过程中的重要参数之一，但由于影响因素很多，精确模型难以建立，所以不易获得满意的控制效果。本文提出一种选择一预测控制方法。通过仿真证明该方法简单、易实现，且有较好的鲁棒性。

Dissolved oxygen is one of the improtant parameter in the process of acid fermentation. It is difficult to control as there are many affecting factors in existence and it is hard to buile an accurate modeling. In this paper, akind of selective predictive control methodisproposed. The simulation examples is given to show that the control method possesses strong robustness and is feasible.
