摘　　要：针对二级管网水力平衡调节阀,在传统PID控制基础上,加入PID参数选择、温度斜率控制、超调量过大处理、边界限制等控制方式,快速、稳定地完成调节阀调节。优化控制后,达到目标回水温度用时4 h左右,比优化前缩短约3 h。超调量得到有效抑制,调节过程快速、稳定。For the hydraulic balance regulating valve of the secondary pipe network,on the basis of the traditional PID control,the control methods such as PID parameter selection,temperature slope control,excessive overshoot treatment,and boundary limit are added to quickly and stably complete the adjustment of the regulating valve.After the optimization control,it takes about 4 hours to reach the target return water temperature,which is about 3 h shorter than before optimization.The overshoot is effectively suppressed,and the adjustment process is fast and stable.
