Fuzzy Control: Setting Membership Ranges

[luca99]

How can I set the ranges of memberships in a fuzzy control? I know my rules, but I don't know how to set ranges, the input of the entire system is a step and after the fuzzy block there is a transfer function and the output.

you're doing that in simulink and using the fuzzy logix block?
simply use the fuzzy logic GUI to implement the rules you have in mind
