What is a closed loop control system and how does it work?

WebOPEN-LOOP GAIN . Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.” For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more. WebCompared with the open-loop control performance, the closed-loop control performance of the stepper motor has the following advantages: With the increase of output torque, the speed of the two decreases in nonlinear form, but the closed-loop control improves the torque frequency characteristic.
