I would like to use this circuit but it can not run as it does not have the FIS file . I can i create one base on this circuit? how to determine the membership function and rules ?
I think if you check an exemple in MATLAB help that could be so helpful to you.
By the way the uploaded file is unreadable
Dear Erica Carmen,
I suggest you to see links and attached file on topic.

First, determine what your input and output parameters are. Next, create a state table for how various input states determine the output (This will help you in creating your rules later). To choose the membership function, it is not usually given as to what shape should be used for any problems but states such as 0 and 1, high and low etc, most authors use Triangular membership function for one and Trapezoidal for the other. But once you're done, you must tune each of the input parameters to see if you obtained a desired output else, you may have to vary membership function for one of the input parameters or even that of the output parameters.. it's all trial and error as no book has suggested any particular shape for any problem. What it simply means is this is a design problem. You design, adjust and redesign till you obtain what you want. Best wishes
Hello @ Erika;
You can type "fuzzy" in command window to run the fuzzy logic designer box then select the input membership function and specify the its range, then it will show the plots automatically. After finishing your design, you save the file then you call it from MALAB Simulink
