Root Locus
4. Describe in your own words what the root locus does, and what information you can obtain about a system from
the root locus.
5. Given the two standard block diagrams associated with root locus analysis, explain, using equations, why the two
systems can be analyzed in the same manner.
6. Given H(s) (or H(z)) and G(s) (or H(z)), or G(s)H(s) or G(z)H(z), sketch the root locus using the five properties of
the root locus. Alternatively, select the correct root locus from a set of possible solutions and justify your selection.
7. Given a root locus for either a CT or DT system, determine, to the extent that you can, values of K for which the
system is stable. Describe what information you may be missing to determine values of K.
8. Explain in your own words the five properties of the root locus, including explanation of why they are properties.
