My model contains various Simulink blocks and one Simscape/SimPower block interfaced with Simulink-PS and PS-Simulink converters.
I found that one of the rare solvers to work with that model is ode15s.
Everything was running fine until the moment I needed to add a Simulink block containing triggered subsystems and rate limiters.
I get a number of signal type errors with the rate limiters. When I force my signal to discrete or continous to get rid of those, I get a "not converging" error and a series of algebraic loop warnings.
The algebraic loops are said to be around my Simulink-PS converters but none of that happens when I take out the block with triggers and rate limiters which is no way near the converters...
I might add that the block with triggered subsystems and rate limiters works fine when integrated in a simpler model with a fixed-step solver. So my guess is that those elements behave strangely with ode15s.
Can someone please help?
Unfortunately I can't upload my model so here are a few screenshots:
