Hi !

I'm trying to replicate a simulation made in a paper on building a fuzzy controler for an HVAC system using Simulink.

I was able to make all the required membership functions, and to create the appropriate rules. I have two input values, and one output value. I have successfully "attached" my .fis file to the fuzzy controler "box". I'm am now trying to create the input and output blocks.

I don't see what kind of blocks I should use. The example in Simulink seems to use numbers as values for the input. However, I thought fuzzy logic was all about using words.

I would like to be able to "tell" my system that it is too hot, or too cold without having to resort to specific values. What kind of input can I use for this, and how can I have two different inputs when there is only one arrow entering the fuzzy controler box ? So far, I've used a mux box, but I don't know how it knows which "value" corresponds to which variable ?

I hope I have been clear enough.

Thank you in advance !
