Hello. Could you help me? The article 1.pdf presents the architecture of the control system and the corresponding block diagram. I want to ask a question: why don't we take into account the PWM (Oscillator) transfer function? I guess I need to add a PWM block as shown in the picture.
Thank you.

Hello,

Perhaps you can post the particular block diagram and their result here so it will narrow down what we have to examine to be able to help.

Well, what is the average of the output of a PWM block?
If you know that, then you know that something very simple can replace the PWM block.
In any case, it will be necessary to replace it with something so you may have to look deeper to find it in your particular diagram they may have considered it so simple they didnt bother to explain it in detail.
There would be one exception to that, and that is if the PWM duty cycles is fixed and then the replacement will be a constant.

If you still have trouble i'll post the usual way of handling this.
