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 ...

To help reduce the challenges associated with cooling solutions, engineers can utilize closed-loop fan speed control ICs (FSC-ICs) over open-loop fan drive ICs. The small geometry IC fabrication ...

An electronic closed-loop control system generally consists of three elements: the controller, the input for the feedback signal (an ADC), and an output actuator (a DAC). The ADC senses and feeds back ...

Open-Loop vs. Closed-Loop So where exactly does open-loop end and closed-loop begin? The line seems clear for some systems, but muddy for others. How much feedback is enough to qualify?

Open-loop systems may not be as smart as closed-loop systems, but they often shine in their simplicity. For the most part, they do what you expect them to do. Light goes on, light goes off.

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 ...
