A unity feedback control system has a plant transfer function

= = G(s) = 100 s(s + 8) We desire to attain a steady-state error to a ramp r(t) At of less than 0.16A and a phase margin of P.M. 35. We desire to have a crossover frequency 20 rad/s. Determine whether a phase-lad or a phase-lag compensator is required.
