A process is described by the exact transfer function below: G(s) = 5/[(15s + 1)(8 + 1)(35 + 1)(0.5s + 1)) (a) Using an appropriate method find an approximate first-order-plus-time-delay (FOPTD) transfer function method. State the method used [Method). FOPTD time constant and time delay calculated are [Tau). (Theta). (b) For a unit step change in input x(t), calculate the response y(t) at t= 12 using the exact model [y-exact-12) and the FOPTD model [y-FOPTD-12]. (c) For a unit step change in input x(t), calculate the response y(t) at t=22 using the exact model [y-exact-22) and the FOPTD model [v-FOPTD-221.
