Webclosed loop control system: A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input. WebApr 23, 2013 · Without this "interrupted" closed loop, AF with third party lenses would only work if their contruction was a Pentax dedicated one. One of the culprits is the precision matching of the screwdrive inside the lens to the specification of the Pentax AF system. The feedback should correct matching errors (resulting in "hunting"). how to evolve fluffeluff
