The second derivative input signals modify which of the following ?
Correct answer: D. The time constant and suppress the oscillations
- A. The time constant of the system
- B. Damping of the system
- C. The gain of the system
- D. The time constant and suppress the oscillations
- E. None of the above
Explanation
Acceleration or second-derivative feedback changes the effective time constant and can improve damping, thereby suppressing oscillations. This is why it is used to improve transient behavior.
