Fuzzy model - Simulink - Parameter Uncertainty

Hello everybody, I built a Mamdani Fuzzy model in Matlab, with five variables fuzzified in membership functions with their parameters (limits of the trapezoid function). I have run it in Simulink for lots of combinations of inputs. I would like to obtain the parameter uncertainty varying the parameter of the membership functions (ie with a MonteCarlo simulation) but I am not able to fit it.. In particular, I do not know how to run simulink changing the fuzzy block (or better, the parameters inside).. Is there a solution? Thank you, Phalaen

You can write a MATLAB script where you vary parameters of a fuzzy system and rerun Simulink model. Let's say you know how to change parameters of an fis system stored in a variable fis.

Once you do these claculations in your script (some sort of "for" loop, let's say), you rerun the model by using sim command .
