摘　　要：针对典型的工业一阶生产过程,采用单值模型算法预测控制,完成了基于PLC的单值模型算法预测控制器的设计,并以过程控制装置为对象,以流量为被控变量,实现了单值模型算法预测控制。实验表明系统控制精度高,抗扰性强,取得了实际误差小于0.01 m3/h的控制效果,运行稳定,具有一定的实用性和推广性。The single value model algorithm expect control is selected for the one-order production process. The single value model algorithm controller based on PLC is designed. This algorithm is carried out by experiments in a fluid level control system on process control equipment. The experiment has shown that this system can run stably and accurately. The error is controlled lower than 0.01 m^3/h. The technology and method adopted in the system is practical and worth spreading abroad.
