A 25 MW combined-cycle cogeneration plant at the University of Connecticut supplies electricity to the entire UConn campus with three natural gas combustion turbine generators and one high pressure steam
In a previous post cascade control was introduced as an effective means of limiting the lag between an upset and the associated PID control loop's correction. As practitioners know: The
Tuning a PID controller doesn't have to be hard. Whether a practitioner chooses to tune control loops manually or with the help of software, the procedure is relatively straight forward
Derivative is the third term within the PID. In mathematical terms the word derivative is defined as the slope of a curve. Seen in the context of strip chart data
Adults can learn a thing or two from children. That's especially true when it comes to matters of time. Whereas adults view it as fashionable to show up to a
It's generally known that the behavior of final control elements (FCEs) (valves, air handlers, etc.) change over time. Like most things the dynamics of FCEs are different from the time
Party hosts often cringe when guests arrive early or late. Seemingly subtle shifts in timing can throw off planned details that are of importance to the host and utterly lost
Among practitioners who tune PID control loops manually most note their focus on calculating the Gain. Process Gain is a model parameter whereas Controller Gain is a tuning parameter. The
Face it, more often than not tuning a PID controller is usually easier when software is applied. While not all products are created equal, the modeling capabilities within most commercial
Level controllers present challenges that are different from others. Although their presence is significant they lag behind Flow controllers in their overall share of the typical production facility's process control
