I get the following error while i try to run my simulation.
I have also tried using a memory block in the feedback line as suggested in few threads but it did not change the result. Pls do drop in your suggestions.

??? Derivative input 1 of 'LinearModel/Plant/Electrical/Integrator1' at time 0.002875 is Inf or
NaN.  Stopping simulation.  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).

Thank you,
