摘　　要：针对在工业生产中连续反应器的运行处于能耗高的问题,依据先进控制理论,以工业连续反应过程为被控对象,依据对象特性,推导了其传递函数,并研究了智能控制算法,给出了控制方案。对控制温度滞后问题,结合传统比例-积分-微分控制与结合预测函数控制,提出PPFC控制方法。该算法结合了二者优点,相比于常规控制,实验结果表明其快速性和稳定性均得到了提高。该算法在西门子过程控制系统(PCS7)中实现,应用于高级多功能过程控制实训系统(SPMT-1000),完成了整个过程控制系统从冷态到稳态的全过程。结果表明智能复合控制算法提升了反应器温度控制的性能,满足生产要求,同时也达到了低碳环保的目的。In industrial production,continuous reactor operation is at a high energy consumption.According to the advanced control theory,the industrial continuous reaction process is the controlled object.According to the characteristics of the object,the transfer function was deduced and the intelligent control algorithm was studied.The control scheme was given.To control the temperature delay,combined with the traditional proportional-integral-differential control and combined with predictive function control,PPFC control method was proposed.Compared with the conventional control,the experimental results show that both the fastness and the stability of the PPFC control algorithm were improved.This algorithm was applied in the PCS 7(Siemens Process Control System),which is applied to advanced multi-function process control training system(SPMT-1000),and completed the whole process from cold to steady state of the whole process control system.The results show that the intelligent compound control algorithm improves performance of reactor temperature control to meet the production requirements and achieves the goal of low-carbon environmental protection at the same time.
