Both of our open-loop control system examples above could easily be converted to closed-loop systems. ... Well, at least in theory. What are they telling you? xkcd #1116.

In classical control theory, both open-loop and closed-loop control systems are commonly used. These systems are well understood and rather straightforward, controlling everything from washing ...

G(s)H(s) = T(s) is called the open-loop transfer function. The magnitude of T(s) is the open-loop gain, sometimes called the loop gain, and T θ (s) is the phase of the open-loop gain or simply the ...

Open-loop heating. Open-loop heating uses manual manipulation to regulate temperature. There is very limited feedback or control features for temperature control. Open-loop heating regulation is ...

An open-loop control process requires human intervention, whereas a closed-loop system is entirely automated (see PID). See process control. Advertisement. THIS DEFINITION IS FOR PERSONAL USE ONLY.
