# Root Locus Analysis & Design

Root Locus Analysis & Design. See attached file for full problem description.

1) Draw the root locus of L (attached). of for positive and negative gain on graph paper.

Find (graphically) the gain, k, to get l = 0.5 for the dominant poles and specify the corresponding corner frequency.

2) Draw the root locus of L (attached) of for positive and negative gain on graph paper. Calculate breakpoints, jw axis crossings and departure angles.

3) Draw the root locus of L (attached) of for positive and negative gain on graph paper.

Find (graphically) the gain k, to get l = 0.5 for the dominant poles and specify the corresponding frequency.
