模型预测控制在火电厂循环水加药控制中的应用

Application of model predictive control to the chemical adding control of circulating water in power plant

以火电厂循环水加药控制为例,采用模型预测算法,研究工业中典型的带有滞后被控对象的控制问题.对该控制方法进行的仿真研究结果表明,系统能有效地避兔纯滞后环节在控制过程中带来的振荡现象,工程应用取得了理想的控制效果.

Taking the chemical adding control of circulating water of a thermal power plant as example, the single val- ue model algorithm predictive control is selected for studying the control problem of the typical controlled-object with time-delayed in industry. This control method has been stimulated and studied in practice. The proposed method of sin- gle value model algorithm predictive control has been stimulated and studied in practice. The results show that the sys- tem can avoid the oscillation, caused by the pure lagging in the control system. Ideal control effect has been obtained by using this method.
