Applying the principles of closed loop PID control to your system fan requirements will eliminate many problems down the road. Darrin Vallis is a principal field applications engineer at Cypress ...

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?

Feedback control methods implemented using low-cost microprocessors enable significant gains for single-phase ac motor speed controls.

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.

The new closed-loop cooling system has helped Process Conversions control process cooling temperatures within plus or minus 3° F, vs. plus or minus 5° F with the old system.
