Question: For the control system shown in Fig below, determine the characteristic equation of the closed - loop response and determine the value of K c

For the control system shown in Fig below, determine the characteristic equation of
the closed-loop response and determine the value of Kc that will cause the system to
be on the verge of instability (i.e., find the ultimate gain Ku). Use the Routh test.
