Question 1
What does a root-locus plot show?
Question 2
At zero feedback gain, where do root-locus branches begin?
Question 3
If a system has more open-loop poles than open-loop zeros, what happens to the extra root-locus branches as the gain becomes very large?
Question 4
As closed-loop poles move closer to the imaginary axis from the left half-plane, what usually happens to the system?
Question 5
Which statement best describes the real-axis rule for root locus?
