For the control system based on the standard feedback control configuration in Fig. 11.8

5 – as G, = G =1 a > 0 G. = K¸ G, (s + 1)3

determine whether the value of a affects the stability of the closed-loop system. Assume K_c > 0. You do not need to solve for the roots of the characteristic equation to answer the question.
