The closed loop fan controller works by comparing desired speed with actual speed and generating a fan command to minimize the difference. In concept, this can be implemented very simply.

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

With a smart controller, the phase angle can be adjusted to provide a linear control feedback. With a closed-loop, smart controller, a true linear speed change can be provided.

With closed-loop control, poor performance typically manifests itself as deviations from set point. By analyzing these deviations, one can determine if they are caused by suboptimal controller tuning ...

The biggest improvement is that AR2 had a closed-loop control system, and AR3 is open-loop. If something bumps the arm or it crashes, the bot will recover its previous position automatically.

Closed loop gain response The circuit as described so far, has been designed to produce a constant output power level. If the detector has a high dynamic range, the circuit can precisely set PA output ...

This new study of pediatric patients with type 1 diabetes from France and Belgium investigated the effectiveness of insulin delivery via closed-loop and open-loop systems.

Manufacturers today face many hurdles in their manufacturing applications. Process parameters can range from one application to the next. While some applications require very little precision and ...
