Which of the following statements is correct for any closed loop system ?
Correct answer: C. Only one of the static error co-efficients has a finite non-zero value
- A. All the co-efficients can have zero value
- B. All the co-efficients are always non-zero
- C. Only one of the static error co-efficients has a finite non-zero value
- D. None of the above
Explanation
For a conventional system classified by type, the position, velocity, and acceleration error constants do not all have finite non-zero values; at most one has that form while the others are zero or infinite. This makes statement c the intended result.
