Figure Q6 (a) Using Routh test determine if the system shown in Figure Q6 will be stable when:
G 1 ( s ) = H 1 ( s ) = 2 G 2 ( s ) = 1 2 s + 2 H 2 ( s ) = 3 s 2 + 3
(b) Discuss how an appropriate Bode plot can be used to determine if the closed-loop system shown in Figure Q6 stable or not. What transfer function should be used to generate this Bode plot?
