The term “control system” in IT is commonly used to refer to systems that control physical hardware processes on a control loop. A control system typically operates on an open-loop or closed-loop model.


Techopedia Explains Control System

The terminology of control systems is confusing, because semantically, in the classical lexicon, a control system was any type of system that controls anything. In the analog age, it was used to refer to thermostats and other physical controllers.

Today, with the focus on digital technologies and state-of-the-art hardware, “control system” is a term used to refer to items like programmable logic controllers that control items like switches, light sensors and other items, many of which are used in a manufacturing or environmental control project. The control system can be thought of as part of the “physical” layers of an IT environment, and tied to the operational control plane rather than the network’s data plane.
