The transfer function of a second order system is _____________________?
Correct answer: A. 1/(T2s2 + 2ξTs + 1)
- A. 1/(T2s2 + 2ξTs + 1)
- B. 1/(T2s2 + 2Ts + 1)
- C. 1/(T2s2 + 2ξT + 1)
- D. None of these
Explanation
The standard normalized second-order transfer function is 1/(T²s² + 2ξTs + 1), where T is the time constant and ξ is the damping ratio. The damping-ratio symbol must multiply the first-order term.
