Simulink || Sawtooth carrier wave distorted at variable-step solver

Hello,

I am designing a converter algorithmically with a PI controller, and I have a simple yet irritating issue so far regarding the solver that I cannot fully understand yet. The issue is that the signals I put through a controller becomes noisy and distorted. I have an image of an A=[0,1] sawtooth wave I generate from a repeatable table unit, and at e-6 maximum step size with no zero-crossing, I obtain a signal that does not always hit minimum or maximum values when it is supposed to, and it even tends to dip.

I believe this is more computer performance related than Simulink configs related, but in case it does not matter, could I ask for tips and hints to correct this noise and distortion problem? This is a very common recurring problem I had to deal with repeatedly for a long time, thus I would greatly appreciate any support on this issue.

Yours truly, Ali

Can you share me the parameter values you have given in Repeating Sequence ?
