Choose the correct combination of the following:
(a) At break-away point the root locus breaks from real axis into complex plane
(b) At break-away point the root locus breaks from imaginary axis into complex plane
(c) At break-in point the root locus enters the real axis from the complex plane
(d) At break-in point the root locus enters the imaginary axis from the complex plane
(b) At break-away point the root locus breaks from imaginary axis into complex plane
(c) At break-in point the root locus enters the real axis from the complex plane
(d) At break-in point the root locus enters the imaginary axis from the complex plane
Show Hint
- (a), (b), and (c) are true
- (b) and (c) are true
- (b) and (d) are true
- (a) and (d) are true
The Correct Option is B
Solution and Explanation
- A break-away point is where multiple roots on the real axis split and enter into complex conjugate pairs.
- A break-in point is where complex conjugate roots re-enter the real axis.
Hence, options (b) and (c) are correct.
