Study on Control Scheme of Reheating Furnace of Steel Rolling Optimization

Abstract

The strategy of temperature control was proposed to achieve the combustion process of steel rolling heating furnace which based on PID algorithm of self-tuning fuzzy parameter with step by step heating furnace of steel rolling as research object and in view of the characteristics of the nonlinear system of uncertainty, many disturbances, big delay etc in the combustion process of heating furnace,starting from the practical engineering in this paper. The method adopts self-calibration of the fuzzy parameters of direct proportion, integral and differential (PID) control. The results show that this strategy of control has some advantages. For example: the speed of response is faster than traditional PID controller, the capability of anti-jamming is stronger than traditional PID controller and the efficiency and quality of the heating furnace combustion process is improved.
