采用DCS控制系统实现串级调节

Application of Cascade Control in DCS

阐述了串级控制在DCS中的应用,并以加热炉温度与流量串级控制为例叙述了串级控制的实现,并从信号传输的角度描述了串级控制系统从DCS到现场的调节过程。

Application of cascade control in DCS was introduced.Taking cascade control of temperature and flow in heating furnace control as an example,the cascade control was established.Regulation process of cascade control system between the site and the DCS were analyzed from the aspect of signal transmission.
