____________ stability method uses open loop transfer function?
Correct answer: C. Nyquist
- A. Ruth
- B. Mikhailov
- C. Nyquist
- D. None of these
Explanation
The Nyquist stability method assesses closed-loop stability from the frequency response of the open-loop transfer function. Routh's method instead uses the characteristic equation, while Mikhailov uses the characteristic-function locus.
