I am not sure if the question even belongs here. Please correct me if it is out of context.

Consider a closed feedback loop. enter image description here

Usually, we say that $K^L(s)$ is a controller over the plat $G(s)$. Is there any reason it is called a plat?

The controlled system may be a car with cruise control, an actual plant, or even the famous F15. These are not necessarily plants. Was the theory originating from real plants and factories?

I am looking for something anchored in resources and not an intuitive explanation.

"Plant" doesn't only refer to the living thing that has chlorophyll; it, in the context of control, refers to a technical system with in and output – some production line, a whole factory, a nuclear power plant.

As such, there's nothing more intuitive than the word itself: a plant is what is being controlled.

  • $\begingroup$ I am familiar with the translation for the word plant and the intuition you gave is my intuition as well. A system under a control loop could be a car (not a plant in this case). I am looking for the origin of the name and not an intuitive explanation. $\endgroup$ – havakok May 18 at 19:40
  • $\begingroup$ hm, for me, a car is a plant, because it's a technical system transforming a physical input into physical output. But if you're actually looking for the etymology of that word, maybe the "english (anglistics)" stackexchange sister site is the right place to ask? $\endgroup$ – Marcus Müller May 18 at 19:52
  • $\begingroup$ I thought it was but I am not sure due to this being a technical name. $\endgroup$ – havakok May 18 at 20:34
