Stabilising time for the controllers is the time required for the response to reach _____________ percent of its ultimate value?
Correct answer: C. 95
- A. 63.2
- B. 87.5
- C. 95
- D. 100
Explanation
In controller response terminology, stabilising or settling time is conventionally specified as the time to reach about 95% of the final value. The 63.2% figure is the one-time-constant response of a first-order system, not the usual stabilising criterion.
