Which of the following methods is the strongest tool to determine the stability and the transient response of the system? Correct Answer Root locus

  • The root locus is the strongest tool for determining stability and the transient response of the system as it gives the exact pole-zero location and also their effect on the response
  • A Bode plot is a useful tool that shows the gain and phase response of a given LTI system for different frequencies
  • The Nyquist plot in addition to providing absolute stability also gives information on the relative stability of stable systems and degree of instability of the unstable system
  • Routh-Hurwitz criterion is used to find the range of the gain for stability and gives information regarding the location of poles

Assertion (A): All the systems which exhibit overshoot in transient response will also exhibit resonance peak in frequency response. Reason (R): Large resonance peak in frequency response corresponds to a large overshoot in transient response.
Assertion (A): It is desirable that the transient response be sufficiently fast and sufficiently damped. Reason (R): Oscillations are not tolerated in the transient response.
