Question

The Nyquist plot of the transfer function $G\left( s \right) = \frac{K}{{\left( {{s^2} + 2s + 2} \right)\left( {s + 2} \right)}}$ Does not encircle the point (–1 + j0) for K = 10 but does encircle the point (-1 + j0) for K = 100 . Then the closed-loop system (having unity gain feedback) is

unstable for K = 10 and stable for K = 100

TuteeHUB · Answer

stable for K = 10 and stable for K = 100

TuteeHUB · Answer

stable for K = 10 and unstable for K = 100

TuteeHUB · Answer

unstable for K = 100 and unstable for K = 100

1.	The Nyquist plot of the transfer function \(G\left( s \right) = \frac{K}{{\left( {{s^2} + 2s + 2} \right)\left( {s + 2} \right)}}\) Does not encircle the point (–1 + j0) for K = 10 but does encircle the point (-1 + j0) for K = 100 . Then the closed-loop system (having unity gain feedback) is
A.	stable for K = 10 and stable for K = 100
B.	stable for K = 10 and unstable for K = 100
C.	unstable for K = 10 and stable for K = 100
D.	unstable for K = 100 and unstable for K = 100
Answer» C. unstable for K = 10 and stable for K = 100

The Nyquist plot of the transfer function \(G\left( s \right) = \frac{K}{{\left( {{s^2} + 2s + 2} \right)\left( {s + 2} \right)}}\) Does not encircle the point (–1 + j0) for K = 10 but does encircle the point (-1 + j0) for K = 100 . Then the closed-loop system (having unity gain feedback) is
