Hi Team,
I am working on the PSIM for the UPS simulation. I want to implement feedback control in converter. Could you please suggest how can we do it?
Below is the block diagram for your reference.
Thanks in advance.

Is there any update on my query?

Hi Team, Is there any update on my query? BR, Grishma
i would recommed that you look at one of the many example circuits.
many of the DC-DC, AC-DC, DC-AC feature close loop control
Also, these design videos are full close loop designs. Adding in feedforward is very straight forward all of the control elements you need are in the control library.
This tutorial video covers a full PFC design in s and z domain
This tutorial video is a buck inner loop
What topology are you trying to control?
Hello Albert,
I designed single-phase full-bridge inverter. I referred Inverter design with average current and voltage loop control | PSIM tutorial video to build this model. It's working fine at full load and no load using a feedback controller (PI).
I want to implement a feedforward control technique for the same inverter circuit.
How we can set gain C(s) for this controller?
Thanks & Regards,

Hi Grishma,
The answer is in the picture you are showing! simply add back in the reference post PI controller. There is a general s-domain transfer function block here in the library.
