To prevent high-gain control and saturations, add a requirement that limits the gain from reference to control signal (output of ...

% Open-loop responses [g,LL,N] = getBlockValue(ST2,'Gain','Leadlag','Notch'); C = N * LL * g; L = getLoopTransfer(ST2,'Notch',-1 ...

The results are similar to those obtained when tuning the controller in continuous time. Now validate the digital controller aga ...

This time, the hybrid response closely matches its discrete-time approximation and no further adjustment of the notch filter is ...
