摘 要: 为了将红外线加热应用于连续退火实验,要求对红外线加热的温度进行有规律的控制·主要介绍所采用的PLC控制理论算法,包括系统辨识、比例积分微分参数整定及优化设计·通过PLC对红外线快速加热炉温度的控制,实现了对试样的快速加热和冷却及温度升降的循环控制,而且升降时间和速度可精确调整,经实际应用取得了良好的效果· The new-style low heat-inertia fast-heating furnace for metal samples is controlled by PID algorithm to exert fast-heating and fast-cooling effects as well as circle control on rise-and-fall temperature on the samples. This system has been proved effective by experiment especially for sensitive adjustment to time and velocity, of which the temperature control theory and optimization design by PLC for system discrimination, PID(proportion-integral-differential) parameter setting, etc., are presented.
