Which of the following is the best method for determining the stability and transient response ?
Correct answer: A. Root locus
- A. Root locus
- B. Bode plot
- C. Nyquist plot
- D. None of the above
Explanation
Root locus shows how the closed-loop poles move as gain changes, so it directly indicates stability and gives transient-response information such as damping and settling behavior. Bode and Nyquist plots are mainly frequency-response methods.
