基于PLC的动态矩阵控制算法实现

Implementing the PLC-based dynamic matrix control algorithm

在介绍了动态矩阵控制(DMC)算法后,重点阐述了DMC在PLC中的实现技术及其应用研究。论文采用PLC实现了上述控制算法,具有更高的可靠性和实时性。仿真及实验研究结果表明,动态矩阵控制效果远优于传统PID控制。文中提出的算法实现可直接或稍加修改应用于实际工业过程。

This paper presents a kind of dynamic matrix control （DMC） and its implementation technique and application study based on the PLC. In fact, the DMC algorithm is carried out by using the PLC, thus achieving high reliability and real -time property. The results from the simulation and experiment indicate that the effect of the dynamic matrix control is much better than that of the conventional PID control. This algorithm can be applied to any real industrial process directly or after a little modification of it.
