Question:
3) The figure shows the root locus of a system G(s), plotted for positive values of K.
) What is the range of K for which Mode 1 is stable in the closed loop?
g) What is the range of K for which Mode 2 is stable in the closed loop?
h) What is the range of K for which the overall system is stable in the closed loop?
i) Find the steady state error to a unit step input, when K = 4, 15, 20.
j) With the use of a pure gain feedback, state which of the following closed loop values of damping ratio 1 are achievable, along with the reason for your answer.
0.28, 0.56, 0.82.
(You are not required to find the value of the feedback gain).
k) With the use of a pure gain feedback, state which of the following closed loop values of
damping ratio 2 are achievable, along with the reason for your answer.
0.28, 0.56, 0.82.
(You are not required to find the value of the feedback gain).
