Consider a unity feedback control system with a plant G(s) = 10 s(s+4) Design a phase-lag compensator Gc(s) such that the static velocity error constant Kv is 50 sec¹ without appreciably changing the location of the original closed-loop poles, which are at s = -2±j√√6. Show the step responses of the uncompensated system and compensated system. Also compare ramp responses at the steady-state.

2. Consider a unity feedback control system with a plant
G(s) =
10
s(s+4)
Design a phase-lag compensator Gc(s) such that the static velocity error constant Kv is 50
sec¹ without appreciably changing the location of the original closed-loop poles, which
are at s = -2±j√6. Show the step responses of the uncompensated system and
compensated system. Also compare ramp responses at the steady-state.
