microcontrollers as a compensator

Hi crazy engineers,

I want to know whether we can use microcontroller as a compensator. Actually my project is about voltage regulation for dc-dc converter using compensators. We were initially looking on using FPGA but it costs much, so the need for an alternative arised. If the task can be implemented please lend me certain ideas of how to implement it.
Eager to see your response.

Thanks folks for your views.😀😀
