THANK YOU ALL

Your feedback is from x. Is that what you want? You do not show any feedback from y. I would think you need both to position the car correctly. You will also need the angle as feedback as well, unless you're parking cars that are shaped like a circle.

yes you are correct the shape appear like circle and i don't want it like that, i try to do feedback for angle and y. But i cannot make it right can you help me please can i communicate you in any application or social networks it more easier from here. thank you and forgive me for my bad ENGLISH language.

Please ask a more specific question than help me.

my question if i add feedback for y before fuzzy control with MUX they give me error because cannot add 3 variable to MUX?

 also second error for fuzzy control ((( Error in port widths or dimensions. Input port 1 of 'test000/Fuzzy Logic Controller' is a one dimensional vector with 2 elements.)))

Can you change your fuzzy controller to accept 3 inputs or at least a 3 element vector? Then change your mux accordingly.
