纯苯是一种十分重要的有机化工原料,具有广泛的工业用途。纯苯塔的塔顶温度是整个工艺流程中的一个重要参数,控制塔顶温度使其恒定在97℃,从而得到高质量的纯苯产品。塔顶温度具有典型的非线性、大时滞及不确定性等特点。介绍了一种基于ARM的模糊温度控制系统,精确度高,稳定性好,适用范围广,实验表明该系统在过程控制中具有较好的控制效果。
Benzene is a very important organic chemical raw material, has a wide range of industrial uses. The temperature of the top of the pure benzene column is an important parameter in the whole process. The temperature of the top of the column is controlled to be constant at 97 ° C to obtain a high quality pure benzene product. The temperature of the top of the tower is characterized by typical nonlinearities, large time delays and uncertainties. A fuzzy temperature control system based on ARM is introduced, which has high accuracy, good stability and wide range of application. Experiments show that the system has good control effect in process control.
