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.

UNDERSTANDING CLOSED-LOOP FAN SPEED CONTROL By Ken W. Gay, SMSC When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables.

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 ...

Titanio series stepper drives from Ever Motion Solutions include three new drives available with two open-loop (no encoder ...

A closed-loop heating system comprises a heat source, means for temperature feedback (i.e., thermocouple), and controller. In a closed-loop heating system, the controller—usually a PLC or a ...
