In order to increase the damping of a badly underdamped system which of following compensators may be used ?
Correct answer: A. Phase-lead
- A. Phase-lead
- B. Phase-lag
- C. Both A. and B.
- D. Either A. and B.
- E. None of the above
Explanation
A phase-lead compensator adds positive phase near the crossover frequency, increasing phase margin and effective damping. It is therefore commonly used to improve a badly underdamped response.
