I am new in simulink. I am trying to model a system including both control and simpower components connecting to each other using "Controlled Voltage Source". I am using continuous ode3 with fixed step of 60 (equal to 1 minute). But after some time the following error appears and simulation stops.
"Derivative input 1 of 'powergui/EquivalentModel1/State-Space' at time 32910.0 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)."
I have not any state-space design in my model but it seems that powergui creates automatically one for its own simulation.
Anybody help me please, I got stock for one week here:(
