A unity-feedback control system has the open-loop transfer

A unity-feedback control system has the open-loop transfer function
G(s) = 4(1 + 2s)
s² (s + 2)

If input to the system is a unit ramp, then steadystate error will be_______

Open loop transfer function =	4(1 + 2s)
	s² (s + 2)

unit ramp
Type 2.
Steady state error = 0
