Hello All,
I spent all morning searching for the error solution on google, so Mathworks and here. I attempted every potential solution I could find: delays, solver changes, saturation, tolerance. I attached the Simulink Power Systems model I have for the verification of my masters research.
While I noticed it originally I dismissed it as I thought Simulink was programmed better with the initial value set, I have narrowed the error down to the voltage measurement origination from the battery model, both the internal and external voltmeter.
Does anyone on here have any idea what settings are required to circumvent this simulation error? Thanks in advance.
Hi Greg
After looking at your model (trying to run it, and solving the warning) I think I found your problem. You need to have at least 1 parallel capacitor in the super-cap block.
NaN are often caused by division by 0, that how I figured out the problem.
few pointer, to amiliorate your model
-When using SimPowerSystem, you should use ode23tb, rather than ode45, due to the stiffnest of your model.
-you should only have 1 Power gui block
good luck in your research

a) the error traces back to the battery control subsystem, from the battery voltage measurement, and nothing to do with the super-cap yet at least.
b) checking my super-cap block I have no parallel capacitors.
c) I did change the solver from ode23tb which I used successfully for the equivalent simscape model. It was throwing that error for that as well
c) both with my prior equivalent simscape, and through my research having a power gui block within each subsystem is allowed.
