Take a look atthis example. It has many of the elements that you are looking for.
Update as of April 2014: his has now been addressed in R2014a, please take a look at thisvideo and thisexample .
People typically run into this situation when they have pwm or some other type of high frequency switching in their model.
You can try to modify your model to not have high-frequency switching (use averaging mode). Please take a look atthis webinar, it should be helpful.
Another option is to use frequency response estimation together with system identification approach.This demo should be very close to what you are trying to do.
