QUESTION 3
For a system G(s) with input R (s) and output Y(s), the error is defined as
KG(s)
E(s) =-
1+KG(s)
O E(s) =R(s) – Y(s)
O E(s) =R(s) - G(s)
O E(s) = Y(s) – R(s)
QUESTION 4
For a system with error E(s), steady-state error is defined as
O ess =e(t)
O ess =e(0)
O ess = lim e(t) = lim sE(s)
s+0
O ess =e(t) when the input i
r (t) = 1(t)
