Number 2 (Root Locus - Compensator) The diagram below shows a system with one pole at s = -3. a. What is the total phase at s0 = -4.2 + j1? b. Now you are asked to apply a compensator with one additional zero and one additional pole, D(s) = K(s + z)/(s + p). Put p and z somewhere on the real axis, so that the phase at s0 will be 180°.
For the given open loop transfer function G(s) = K(s + 4) / [s(s + 6)(s^2 + 4s + 8)] a) Find the poles and zeros of the open loop system b) Locate the open-loop poles and zeros on the complex plane c) Find the number of asymptotes and their angles d) Calculate the real axis crossing of the asymptotes e) Find the breakaway and break-in points on the real axis. f) Draw the Root Locus.
