Today on Hackaday Dictionary, we’re going to talk about the two basic types of control systems: open-loop and closed-loop. We’ll describe the differences between them and explore the various ...

Many variables There are many variables to consider when deciding between an open-loop or closed-loop heating control system for an industrial application. Both methods offer great benefits, but ...

Open loop cooling systems use water to cool engines directly, while closed-loop systems use marine coolant and a heat exchanger to keep engines cool.

Though simple, this “open loop” form of fan control has disadvantages. Since there is no feedback mechanism, speed accuracy depends entirely on mechanical tolerances of the fan. Although it may not ...

So the question is this: is an open-loop system more valuable than a closed-loop system if it means having more control over the process? Does it depend entirely on the process in question?

It is estimated that 40% to 60% of the ac motor applications would benefit from some form of closed-loop, smart speed control.
