Deadbeat control Space-State System

Hi, I'm trying to test a deadbeat control (I'm a learner so please explain if you find conceptual issues as well :) ). To do that I found the gain with the acker command by setting all desired rooths in z=0. I believe this controller is used only in discrete systems. I just used it thanks to the Zero-order holder in Simulink.

Is that fine? Or is there any other fancier way to get the answer of the controller?
