Typical specifications for design stipulates the gain margin and phase margin to be respectively__________________?
Correct answer: A. > 1.7 and > 30°
- A. > 1.7 and > 30°
- B. 30°
- C. < 1.7 and 1.7 and < 30°
Explanation
Common control-system design targets require a gain margin greater than about 1.7 and a phase margin greater than 30° to provide adequate stability reserve. Only option A states both requirements correctly.
