QUESTION 4 50 points Save Answer A process is described by the exact transfer function below: G(s) = 5/{(15s + 1)(8 + 1)(3s + 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 [y-FOPTD-22].
