I was trying to design a PI compensator for integrator plant , which works well in continuous and discrete domain with a step input. I have used the same design with the inputs changed(Sinusoidal). But this time my continuous model works , while discrete domain fails to get me results. Advice will be highly appreciated

Can you share your controller, both in continuous and discrete domain?

file is attached containing continuous and discrete version. Used Tustin method to convert to discrete with sample time of 0.001s
