摘　　要：针对加热炉温度的控制过程具有非线性、时变和时滞等特点,提出一种基于模糊PID的算法应用于轧钢生产线蓄热式煤气加热炉温度控制中。建立了蓄热式煤气加热炉的数学模型,基于PLC技术设计了加热炉温度控制系统,通过Matlab平台验证了模糊PID控制系统的有效性,对工程的实践应用具有一定的理论价值和现实意义。Because the control process of reheating furnace temperature is nonlinear, time-varying and time delay, a fuzzy PID algorithm is proposed for the temperature control of regenerative reheating furnace. The mathematical model of the regenerative gas heating furnace is established, and the heating furnace temperature control system is designed based on PLC technology. Finally, the effectiveness of the fuzzy PID control system is verified by Matlab platform. It has certain theoretical value and practical significance to the practical application of engineering.
