i need to design a fuzzy controller which can compare actual running model with multiple faulty models and detect and identify the faulty model with the running model if some fault is introduced in actual model.
When working with Fuzzy systems you have to think on it as a black box that you will have input information (that in the case of a fuzzy controller can be the controlled variables) and this box will get you the manipualted variable value for the controlled set. use the fuzzy toolbox in matlab to create the fuzzy component and if you want to incorporate it as a controller you can manipulate the output information such as creating an error in order to use it in a PID controller. That is one option.
