摘　　要：磨煤机的工作性能与进料配比关系密切。针对原煤在水分、灰分、挥发分和可磨性方面的特征差异,设计了基于模糊控制理论的磨煤机进料控制单元。通过应用模糊控制理论,对PID控制参数进行优化,实现了磨煤机工作过程的自动调节,提高了磨煤机的工作性能。文章重点阐述了模糊控制器的设计和PID参数的优化过程。There is a close relationship between the performance of ball grinder and feeding ratio. Aiming at the charac- teristic differences of water content, ash content, and grindability in raw coal, the feeding control unit of ball grinder based on the fuzzy control theory was designed. By the application of the fuzzy control theory, PID controlling parameters are op- timized, thus the automatic adjustment of the working process is realized and the performance of ball grinder is highly im- proved. The paper mainly described the design of the fuzzy controller and the optimization process of PID parameters.
