16.9. For each control system shown in Fig. P16-9, determine the characteristic equation of the closed-loop response and determine the value of K, that will cause the system to be on the verge of instability (ie., find the ultimate gain K.). If possible, use the Routh test. Note that the feedback element for system B is an approximation to e System A: System B: K K 1+8 (8s+1) (8x+1)
