Why MATLAB crashed while running PV based boost converter simulink model

MATLAB simulink crashed while running model based on PV array system with boost converter. When I changed irradiation of PV array it crash simulink model and also closed MATLAB. Initially i used stair function then tried with manually constant block during running model.

Dear,

This kind of problem rarely occurs.

And it occurs due to improper design of system parameters ( Such as inductive or Capacitive filter values).

I will suggest that please follow the standard research papers/book to calculate the system design parameters.

Kindly notice it.

Thanks

Thanks for cooperation. Its working when i changed capacitor value according to demand or load of system.

I had this same problem. I fixed it by breaking the algebraic loop. The model ran fine up until this afternoon when MATLAB/Simulink started crashing when I compiled breaking the algebraic loop. Unsure why still and cannot find a solution.
