Hi everyone can anyone help me designing average current mode control of boost converter. I have design the circuit in MATLAB simulink but Output voltage is not coming the exact value .
Please notify me the mistakes which i have made in attached model .
Thanks .
Dear Shafquat Hussain ,
in my opinion you should change the sampling time. Since the switching frequency is set to 100 kHz the Ts value should be 1e-7 for example.
The controll structure seems to be incorrect too.

Sir Lukasz Niewiara, Please Notify me where is my mistake in the Model? and what Should I do to correct that mistake
Thanks
There are a couple of issues that you can complete before I check the logic:
1. The ports of your diode and MOSFET are not connected to scope.
2. There is a switch at the bottom left corner which do not have a switching sequence. These need to be completed otherwise the porgram will not run
3. You also need to change your sample time by going into the discrete solver and change it based on the switching frequency.
First complete these then I will be able to check it in more detail.
Sir Syed A. Raza, here I attached the correct and improved model , but the the converter doesn't boost up the voltage !!! why whats wrong in it please correct this model and notify my mistake
Thanks
Regards Shafquat
