Feedback Flashcards
An increase in negative feedback ……………… sensitivity
Decreases
Negative Feedback
Increases stability but makes the servo unresponsive to small changes.
An increase in velocity feedback will …………….. the speed at which the load moves
Decrease
Velocity feedback
Opposes demand input therefore reducing the speed at which the load moves
Tachogenerators provide what feedback?
Rate feedback
If feedback is anti-phase it is said to be?
Negative feedback
Positive feedback applied to a servomechanism ……….. the response of the system
Increases
What type of feedback would be used to prevent overshoot?
Rate feedback
To reduce overshoot errors in a synchro
The system will have velocity feedback
To increase the output of a servo amplifier, it is necessary to
Reduce the tacho feedback
Position feedback from a potentiometer is
Anti-phase
Why is the position feedback anti-phase?
To oppose the demand input
Positive feedback - Phase or anti-phase?
In phase with the input
Positive feedback applied to a servomechanism, …..………. the response of the system
Increases
An increase in negative feedback to the servo amplifier
Increases amplifier stability
