Loop gain - Wikipedia

WebIn amplifiers, the loop gain is the difference between the open-loop gain curve and the closed-loop gain curve (actually, the 1/β curve) on a dB scale. See also. Phase margin and gain margin; Nyquist plot; In telecommunications, the term "loop gain" can refer to the total usable power gain of a carrier terminal or two-wire repeater. WebClosed-loop control uses the real-time position and stator current feedback to tune the speed controller and the current controller and change the duty cycles of the inverter. This ensures that the corrected three-phase voltage supply (that runs the motor) corrects the motor feedback deviation from the desired value.
