单值模型预测控制的应用研究

Application of Single-value Model Predictive Control Algorithm

传统的模型预测控制算法的计算时间比较长 ,一般需要较长的采样周期 ,本文针对工业过程中大量存在的过阻尼对象提出了单值模型预测控制算法 ,并在PTA生产的浆料浓度控制中进行了应用。单值模型预测控制算法实施简单、容易在DCS层实现而且可以获得良好的控制品质。

The traditional model predictive control need long sample time for its long computer time. In this paper,single-value model predictive control for over-damp system was presented and applied to control slurry density system. The algorithm is simple and can get good control performance.
