650t/h直流炉再热汽温的自适应预估控制

Adaptive Prediction Control For The Reheater Steam Temperature of a Once-Through Boiler

在文[1]的基础上,本文提出了一种离散时滞系统自适应预估控制算法,并应用于一台650t/h直流炉再热汽温的控制。该系统具有明显的参数时变和多干扰等特点,曾长期处于手动运行状态,引入自适应控制后,得到了良好的控制效果。

Based on paper [1], an adaptive .prediction Control algorithm for discrete systems with time delay is proposed, and it has be successfully applied to control the reheating steam temperature of a 650t/h once-through boiler in power plant. The controlled process is so characterised by suffering strong disturbarces and time-varying that the conventional control scheme originally designed for this process can still not be put in operation. By application of the adaptive prediction control method, the satisfactory control results have been achieved.
