Question 2 (10 marks) Consider the feedback loop shown in Figure Q2 u K V G(s) Figure Q2: Closed-loop System where the transfer function representing the plant is (5+1) G(s) 8(6+ 58 - 6) (3 marks) (a) Show that the open-loop system (i.e. the transfer function G(x)) is unstable, (b) Show that the characteristic equation of the closed-loop system is 33 +58 + (k - 6) + k = 0 and use the Routh-Hurwitz criterion to find the range of values of k for which the feedback system in Figure 02 is stable (7 marks)
