Consider the feedback system in Figure 2.74 with

Ge(s): K(s +0.3) = H(s) 2s, and G(s) = S 1 (s2)(s + 10s+45) Assuming R(s) = 0 and N(s) = 0, the closed-loop transfer function from the distur- bance Ta(s) to the output Y(s) is: Y(s) a. 1 Ta(s) $3+852 + (2K+25)s+ (0.6K - 90) Y(s) b. 100 Ta(s) s3+852 + (2K+25)s+ (0.6K - 90) Y(s) c. Ta(s) d. Y(s) = 1 8s+(2K+25)s+ (0.6K - 90) K(s+0.3) Ta(s) s+8s3+ (2K+25)s + (0.6K - 90)s
