Suppose you are given the system depicted in Fig. 4.33(a), where the plant parameter a is subject to variations

(a) Find G(s) so that the system shown in Fig. 4.33(b) has the same transfer function from r to y as the system in Fig. 4.33(a).
(b) Assume that a = 1 is the nominal value of the plant parameter. What is the system type and the error constant in this case?
(c) Now assume that a = 1 + δa, where δa is some perturbation to the plant parameter. What is the system type and the error constant for the perturbed system?
