Abstract
In view of problems of wasting too much fuel,serious pollution of coal-fired reheating furnace caused by difficult temperature control,a heating system model of coal-fired reheating furnace with multi-temperature zones was established.A feedforward decoupling control method based on PID control algorithm was proposed.The method uses feedforward decoupling control to realize decoupling for coupling parts of each heating channel,which can reduce the time required for the heating system to reach steady state,and uses PID control algorithm to optimize control parameters of the heating system,which can make temperature of the heating system rapidly rise and remain stability in a short time.The simulation and experimental results show that the method can greatly improve temperature control speed,and can achieve stable control accuracy in a shorter response time,which avoids fuel wasting and improves heating rate.关键词
