derivative of state '1' in block 'FOPID/Fractional PID controller/Fractional derivative1/Transfer Fcn1' at time

0.01408153786115585 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try

reducing the step size (either by reducing the fixed step size or by tightening the error tolerances) .
