Question

A unity feedback system has loop transfer function:

      L(s) = Gc(s)G(s) = 4(s+z)/s(s+1)(s+3)

a) Draw root locus as z varries from 0 to100

b) using root locus, estimate the percentage        overshoot and settling time (within 2%) of        system at z =4

c) determine actual overshoot and settling             time at z = 4
