Root Locus - 3

Example 1

For this system, answer the following questions:

1)    Make a pole/zero plot.

2)    How many closed-loop poles are there?

3)    What are the closed-loop poles for K = 0?

4)    What are the closed-loop poles when K = ¥?

5)    Are there any infinite closed-loop poles for any K, 0 <= K <= ¥?

6)    Make a guess at the system's root locus and draw it in on your pole/zero plot.

7)    Is the system oscillatory and, if so, for what values of K?
