Hi
You will have to design compensator for the worst-case scenario. Make sure you have the phase margin more than 45 digress when the CTR has a variation 0.05 to 0.6.
First enter a CTR value of 0.05. And design the compensator. For next step keep the same compensator values and change the CTR to 0.6 and observe the phase margin.
