In servo-system, the device used for derivative feedback is known as:
A. Synchro
B. Servomotor
C. Potentiometer
D. Tacho generator
Answer:D
In servo-system, the device used for derivative feedback is known as:
A. Synchro B. Servomotor C. Potentiometer D. Tacho generator
Explanation: Tacho generator provides the derivative feedback when used in a servo system and it controls the speed of the servo-system by providing the value of the speed as feedback.
