Question 7 Consider the following unity feedback system: R(S) C(s) 10(s + 1) s(s+5) Select the correct steady state error when the desired response is: r(t) = (5 – t +0.5t?)1(t) where 1(t) is a unit step function: = ess lim e(t) = 0.5 t-00 ess = lim e(t) = 0 t-100 o ess = lim e(t) = 1 t-100 O ess = lim e(t) = 2.1 = t-00 ess = lim e(t) = 0 t-00
