Please please go step by step to show how they got T(s) and G(s)... Eish it confuses me!
A feedback system shown in Figure 5 has a the forward path transfer function G(s) and the feedback transfer function H(s) given by 647 S+ 5 G(s) = H(s) = (s +19)(s + 7) S + 11 r(t) u(t) y(t) G(s) H(s) Figure 5: Determine the following; 5.1 The equivalent forward path transfer function G(s) for a unity feedback sys- tem. 5.2 The steady state error, when the input is 2 tu(t), where u(t) is a unit step func-
