I have set of fuzzy membership functions and fuzzy rules in the form of if-then rules. I am getting only one output at a time by defuzzying the rules. But I want to iterate all the rules again for updating the input values to get the updated output value. For dynamical models I need to iterate these rules for at least 'n' number of times. Does anybody knows to do this iteration. I am not asking about iterating rules from data, I am asking about iterating the existing fuzzy rules. If possible anyone can suggest the tool for this iterative procedure to get the output data.
