The cascade loop in the acid gas removal unit shown in figure 11 has a master pressure control loop and a slave flow control loop. The pressure loop responded poorly to regular disturbances from the ...

The application almost always determines whether open- or closed-loop analog control is used. Many applications will work with on-off, closed-loop control using an analog sensor measuring temperature, ...

A common example of a cascading PID loop is 3-Element drum level control where the primary loop uses the drum level, setpoint, and steam flow to determine the feedwater flow setpoint for the secondary ...

Over 150 years ago, one of the first attempts to thoroughly describe control loops using feedback took place in James Clark Maxwell’s article, On Governors. 1. In control strategies, an open-loop ...
