Question

According to Nyquist stability criterion, where should be the position of all zeros of $G(s)$ corresponding to $s-plane$?

• A. On left half
• B. At the centre
• C. On right half
• D. Random

Hint:

In the Nyquist plot, ensure that all poles are in the left half-plane for system stability.

Answer 1

The Correct Option is A

According to the Nyquist stability criterion, for a system to be stable, the poles of the transfer function \( G(s) \) must lie in the left half of the complex \( s \)-plane. This ensures that the system's response does not diverge or become unstable. Zeros should also be placed in the left half to maintain stability.
