6. For the control system shown in the following figure R(s) C(s) k,(1+r,s), k, T+1 Determine a) Damping coefficient and the time constant of the system- b) If a proportional controller only is used, and the system become critically damped, !! what is the controller gain, knowing that ki = 0.29 k2-1, t = 60 sec, and t = 10 sec 6.
