Consider the following unity feedback control diagram: R(S) + s C(s) K(s + 1) 1 (S + 2) (S – 1) Investigate closed-loop stability of this system for the two cases where K = 1 and K = 3: Unstable for K=1 and unstable for K=3 Stable for K=1 and stable for K=3 O Unstable for k=1 and stable for k=3 Stable for k=1 and unstable for k=3
Select the correct statement about the root locus of the following system: R(s) + C(s) K(s + 1) S2 + 5s + 17.33 When K goes to +00, two branches of the root locus end at -1 and one remaining branch goes to infinity approaching an asymptote. The root locus has two branches and point s=-0.2 on the real axis belongs to the root locus. O None of them are correct. The root locus has three branches and point s=-2 on the real axis belongs to the root locus. For K = 0, the root locus begins at s=-1 and when K goes to +00, two branches go to infinity approaching asymptotes.
