摘要
本文应用自动控制理论“自适应在线辨识”解决了混凝土大坝混凝土一、二期冷却的自动控制问题。通过预埋的电阻温度计实时量测温度,实时调节循环冷却水系统的流量和水温或是毋须进行通水,以便达到良好的冷却质量和经济节约的目的。
The automatic control theory of'The on line identification of self-adjusting control'is adoped to resolve the automatic control problem of first and second stage cooling of concrete in large concrete dam construction.The temperature of dam body was measured by preembedded electric rosistanca thermometers.Raal time regulation of discharge and temperature in circulating cooling water was undertaken.Proper planning of cooling water system or without it,can obtain cooling of good quality and econo-mical results.
