摘要

针对现有集中式温度支路平衡控制存在的问题，提出基于分布式偏差的支路温度一致性控制方案：仅利用相邻支路的温度信息，将各支路与相邻支路的温度偏差作为控制输入，使加热炉所有支路的温度达到一致的同时，确保调节过程中总进料流量不变。由于仅利用了相邻支路的温度信息，使得所提分布式偏差控制方案在大规模支路情形下更显优势。最后仿真实例表明了该分布式控制方案的有效性与可行性。

Abstract

A novel design method was proposed on the basis of distributed deviation for consensus pass temperature control on industrial feed heaters

in order to overcome limitations of centralized balance control schemes on pass temperatures. In the method

only temperature deviations of adjacent passes were used as input in control algorithm to achieve uniform temperature across all passes while maintaining constant total feed flow. Compared to the traditional centralized balance control

this distributed deviation control scheme by using only temperature information of adjacent passes was more cost effective especially for cases with large number of passes. Sufficient conditions for the distributed deviation controller on industrial feed heaters with time delay and random disturbance were derived by Lyapunov function. The simulation results illustrated that the new controller design method was effective and the distributed deviation control scheme was feasible even for a class of industrial feed heaters with mismatched models.
