The forward transfer function of a system is 10/1 + s. The steady state error to unit step input when operated as a unity feedback system is—

Given that

G(s) =	10	, H(s)=	1
	1 + s		s

r (t) = u (t)
then R (s) = 1/s

e_ss = _{s → 0}Lim .sE (s) =_{s → 0}Lim	s.R(s)
	1 + G(s) H(s)

=_{s → 0}Lim	s.1/s	=	1
	1 + 10/1 + s.1		11
