The Research of Fuzzy Control On Through Hole and Vertical Pit Heating Furnace (Liu Huikang, Yang Bin) (College of information science and engineering, Wuhan university of science and technology, 430081,Wuhan, Hubei, China) Abstract A through hole and vertical pit furnace’s structure and characteristics are introduced in the paper. According to the characteristics, a double fuzzy controller is put forward and applied to temperature control of the heating furnace with special structure. Result of research and project in practice shows that the double fuzzy controller based on input of model reference applied to the through hole and vertical pit furnace can gain better dynamic and steady state performances. Key words: a through hole and vertical pit furnace;a double fuzzy controller;model reference
