The centroid in the root locus is a point where

Electronics and Communication Engineering (ECE) : Automatic Control Systems - Quiz(MCQ)

The asymptotes cross the real axis.

The branches of the root locus tend to infinity.

The branches of the root locus terminate on the real axis.

The branches of the root locus intersect with the imaginary axis.

Correct Answer : Option (A) : The asymptotes cross the real axis.

Explanation : Centroid is defined as a common point where all the asymptotes intersect on the real axis. The value of centroid is always real. But, it can be located either on the positive or negative real axis.
