E7.14 A unity feedback system has the loop transfer function

L(s) = Ge(s)G(s) = K(s+15) s(s+3) (a) Determine the breakaway and entry

L(s) = Ge(s)G(s) = K(s+15) s(s+3) (a) Determine the breakaway and entry points of the root locus, and sketch the root locus for K > 0. (b) Determine the gain K when the two characteristic roots have a of 1/2. (c) Calculate the roots.
