loop gain

[′lüp ‚gān]
(control systems)
The ratio of the magnitude of the primary feedback signal in a feedback control system to the magnitude of the actuating signal.
(electronics)
Total usable power gain of a carrier terminal or two-wire repeater; maximum usable gain is determined by, and may not exceed, the losses in the closed path.

The variation in output current [I.sub.o] caused by [[??].sub.g] can be alleviated by increasing the magnitude of the loop gain T(s) when the closed-loop control design is integrated with the SRC# plant model.
The loop gain A[beta](s) of the proposed controllable constant power generator is given by
As the poles come closer to origin, the bandwidth becomes narrow, the open loop gain for the system is high and the integral gain is lower compared to that with a remote pole location in s-plane.
Due to the large effective inner loop gain of this hybrid expansion valve, superheat control of a single evaporator was greatly improved.
And then low loop gain [K.sub.1] = 0.50 in cascade is selected and high loop gain [K.sub.2] = 2.587 in cascade is selected for the system which is just in the sustaining oscillating condition.
The model can be equivalent to a Miller FD, and its locking range is determined by the frequency range where the loop gain exceeds one [13].
In theory the 6-wire remote sense configuration removes all errors except for the finite loop gain error and the input offset error associated with the current meter.
(6), where DG is the amplifier Direct Gain between input and output; OLG is the Open Loop Gain; [G.sub.0] is the amplifier gain; and B is the loss of the resonator.
Important components likely include pharyngeal anatomy (38,39), pharyngeal dilator muscle responsiveness to respiratory challenges during sleep (40-43), the arousal threshold (propensity to wake up from sleep) (44,45), the instability of the negative feedback control system regulating ventilation (loop gain) (46-48), and upper airway tethering via caudal traction from changes in end-expiratory lung volume (EELV) (49-52).
Guneralp (2006) suggested using the terms on the right-hand side of (7) as weights to combine elasticities of individual behaviour modes [[epsilon].sub.i] with respect to some system element (like a link gain or a loop gain) into a weighted sum as a measure of the overall significance of that system element.
