摘　　要：高炉电气设备启动控制的主要作用是控制高炉电气设备的启停和运行状态,以确保高炉的正常、安全、高效运行。通过启动控制,可以减少高炉电气设备的损耗和故障率,延长高炉电气设备的使用寿命,提高高炉的生产效率和运行稳定性。同时,启动控制还可以实现对高炉电气设备的监测和管理,及时发现并处理设备故障,保证高炉的安全性和可靠性。设计基于模糊PID的高炉电气设备启动控制系统。以单片机作为核心,设计复位、时钟以及接口电路硬件结构;明确模糊PID参数与偏差导数之间关系,建立模糊参数自整定控制结构,实现对高炉电气设备启动过程参数的控制,并基于主程序、子程序以及中断程序,完成软件结构设计。实验表明:该系统的控制精度更高、超调量较小,使得控制误差较小,可利用该系统控制高炉电气设备,促进工业高炉生产。The main function of starting control for blast furnace electrical equipment is to control the start,stop,and operation status of blast furnace electrical equipment,in order to ensure the normal,safe,and efficient operation of the blast furnace.By starting control,the loss and failure rate of blast furnace electrical equipment can be reduced,the service life of blast furnace electrical equipment can be extended,and the production efficiency and operational stability of the blast furnace can be improved.At the same time,startup control can also achieve monitoring and management of blast furnace electrical equipment,timely detection and handling of equipment faults,ensuring the safety and reliability of the blast furnace.Design a start-up control system for blast furnace electrical equipment based on fuzzy PID.Using a microcontroller as the core,design hardware structures for reset,clock,and interface circuits;Clarify the relationship between fuzzy PID parameters and deviation derivatives,establish a fuzzy parameter self-tuning control structure,achieve control of the start-up process parameters of blast furnace electrical equipment,and complete the software structure design based on the main program,subroutine,and interrupt program.The experiment shows that the control accuracy of this system is higher and the overshoot is smaller,resulting in smaller control errors.This system can be used to control blast furnace electrical equipment and promote industrial blast furnace production.
