Consider a control system with the open loop transfer function given by: GOL(s) = Kce-0.3s / (1.5s+1)
In the above function, pre-factor of s is in minutes and Kc is the gain of proportional controller. The frequency for phase margin of 30° is 4.04 rad/min. The value of Kc for a gain margin of 1.7 (up to one decimal place) is _______.
