Unformatted text preview: E 462 Vibrations, Controls, and Optimization II Spring 2010 b. [5 pts] What compensator design would you use to move the closed loop poles to s = ‐3 +/‐ 2j instead? Circle the correct answer and state a reason for your answer. Gain Only PI PD c. [5 pts] Your friend from Berkeley tells you that adding a zero to the root locus plot along with a gain K (Gc = K(s+z)) will be able to move the closed loop poles to the desired locations s = ‐3 +/‐ 2j. Find a zero location that would work with this compensator. The root locus is repeated below for convenience.
