讨论了双层控制结构的特点，并基于这种控制结构，采用广义开环响应控制算法（ＧＯＲＣ），设计了催化裂化装置解吸塔温度的先进控制回路。应用结果表明，它不仅明显改善了控制性能，而且操作方便、安全可靠。
Based on this control structure, a generalized open-loop response control algorithm (GORC) is used to design the advanced control loop of the temperature of the desorber of FCC unit. Application results show that it not only significantly improve the control performance, but also easy to operate, safe and reliable.
