Digital PID control of buck-boost regulator

[tariqusman1]

Respected Members,

I have tried to simulate the classical buck-boost regulator in simulink with PID control but it is not working as it should be. So I need some assistance in this regard. I have downloaded the buck regulator with PID from mathworks it is working fine and the boost is also working fine, but the buck-boost i have made is not working as expected.

Furthermore, if somebody know how to make a mathematical model of Buck-Boost regulator in simulink then it may also resolve my problem of designing a PID compensator. I also need to know the equations required to design the buck-boost regulator. Since I have the buck regulator mathematical model so I will try to learn from the example of buck-regulator mathematical model.

Yours sincerely
Tariq

Hey Tariqusman, i am also facing the same problem. I am unable to design pid for buckboost but for buck and boost it is fine and unfortunately i am unable to resolve the issue. Could u please help me yaar? Did you get any idea where we are going wrong. Kindly please help me. I am waiting for your reply.
