摘　　要：为了进一步实现蓄热式热处理炉温度控制,从加热炉的工艺流程角度首先设计了PID控制的传递函数,并就其参数整定进行了分析,根据模糊规则对偏差和偏差变化率实现PID参数在线修改。MATLAB炉温控制验证表明,所设计的各阶段PID参数均保持在最佳情况,实现了PID参数在线自整定,获得了满意的控制效果。To realize temperature control in regenerative heat treatment furnace, first designing the transfer function of the PID control from the process flow of the furnace, and analyzing its parameter tuning, the error and error change rate of the PID parameter were modified on-line according to the fuzzy rules. The verification of MATLAB temperature control show that the designed PID parameters in each stages are all maintained in the best case, which can realize self-tuning of PID temperature parameters, and obtain satisfactory control results.
