A new controller of heat treatment furnace based on fuzzy-PID

LIU Yu,WANG Ke-cheng (School of Electronic and Information Engineering,University of Science and Technology Liaoning,Anshan 114051)  
A new automatic adjustment controller of heat treatment furnace was designed based on fuzzy control and PID parameter self-turning in accordance with the requirements of on line self-adjustment control with higher steady accuracy and shorter adjusting time.By analyzing the heat treatment furnace model,the control rules were determined.Meanwhile,the simulation on the new automatic adjustment controller and conventional controller was made.The result indicates that the new controller only requires 24 seconds to adjust;it also has a slighter overshoot and less steady state errors;it's better in effectively controlling the temperature,which can provide more accurate technical support to rolling process in heat treatment furnace.
