The Heat Treatment Furnace Automation System Based On Intelligent Control
Pan Haipeng (Department of Automation, Zhejiang Institute of Science and Technology, Hangzhou 310033) Abstract: Through the analysis of current status and technique difficulties for Heat Treatment Furnace control, this paper puts forward a new plan that combines nonlinear fuzzy controllers with linear PI controlers to control furnace temperature. By NN empty combustion dosing ratio optimization technique to realize combustion optimization. This paper resolves automatic temperature setting of furnace for every segment based on mathematics model and expert system. Then the automatic intelligent control of the whole heating process is realized. Application shows that the system has good reliability, high control precision and obvious energy conservation effect. The results can be extended in industry heating furnace control.
