摘　　要：为了动态监测反应器生产过程内部状态和更精确控制反应器温度,采用了基于PCS7扩展卡尔曼滤波器功能块和动态前馈控制的方法。对反应器进行机理建模、通过软传感器测量反应器内部状态不可测参数,对传感器数据进行卡尔曼滤波预测估计,利用软测量得到的反应热实现对反应器温度执行动态前馈控制等实验,实验结果能够实时监测反应器建模内部状态、通过软测量得到反应热等数据,实现了反应器温度控制更加快速、平稳和精确。In order to dynamically monitor the internal state of-the reactor production process and more accurately control the reactor temperature.The method based on PCS7 extended Kalman filter function block and dynamic feedforward control is adopted.The mechanism modeling of the reactor is carried out,the unmeasurable parameters of the internal state of the reactor are measured by soft sensors,the sensor data is estimated by Kalman filter,and the dynamic feedforward control of the reactor temperature is realized by using the reaction heat obtained by soft sensors.The experimental results can monitor the internal state of the reactor modeling in real time,and obtain the reaction heat and other data through soft sensing,so that the reactor temperature control is more stable and accurate.
