Once designed into a system, closed loop fan control can solve the previously described issues. Beat frequencies from slightly out of sync fans are easily eliminated. Precise RPM control also allows ...

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 ...

When examining the proportional control mode and the integral control mode, their actions are based on the assumption that a fairly fast control process was discussed. The discussion was made simpler ...
