摘　　要：针对间歇反应釜降温时间控制困难的问题,提出一种基于间歇反应釜降温数学模型的控制方案。该方案依据热量守恒定律和传热速率方程建立间歇反应釜降温数学模型,通过控制间歇反应釜夹套入口冷媒的温度,进而实现对间歇反应釜降温时间的控制。为了实现反应釜在目标时间内降温至目标温度的多目标控制目的,采用了基于模型的开环控制闭环修正的控制策略,通过周期性修正间歇反应釜降温模型,实时调整夹套入口冷媒的温度,从而实现间歇式反应釜降温过程的多目标控制,提高了降温时间的控制精度。并通过实验证明该修正方法及控制方案是切实可行的。It is difficult to control the accurate time of cooling process in a batch reactor. In order to overcome this difficulty,a control scheme is put forward based on the cooling mathematical model of batch reactor. In this scheme,the cooling mathematical model of batch reactor is firstly established according to the law of conservation of heat and the heat transfer rate equation,then the cooling time of batch reactor is controlled through controlling the coolant temperature at jacket entrance of batch reactor. In order to realize the target of multi-objective control that the batch reactor is cooled to an objective temperature in an objective time,the control strategy of open-loop control plus closed-loop correction based on the mathematical model is adapted,therefore the coolant temperature at jacket entrance is adjusted in real time through modifying periodicaly the cooling mathematical model of batch reactor. The multi-objective control of cooling process in batch reactor is finally achieved while the control accuracy of cooling time is improved too. This modified approach and the control scheme is verified practicable according the experimentations.
