M.F. for IP & OP with trimf & guass

Intelligent Environment Systems  Similarly built other MF relationships for inputs and outputs in guassian curves and triangular MFs.  Inputs : Inside Temperature, Outside Temperature, Season, Time of the Day, Specific Heat of Air and Humidity.  Outputs: Ventilation, Lighting, Soil Moisture, Heating.

Intelligent Environment Systems 39 rules

Intelligent Environment Systems Output: Heating

Intelligent Environment Systems Output: Lighting

Intelligent Environment Systems Output: Ventilation

Intelligent Environment Systems Output: Soil Moisture

Intelligent Environment Systems Fuzzy Evaluation of Outputs for given Inputs.  Graphical: Use the rule viewer to shift input parameters as desired and corresponding output parameters are changed  Using C code: A = readfis (‘greenhouse’) Out = evalfis ([time otemp hum seas intemp spair], A) That is Out = evalfis ([ ], A) Out = ventheatlightsoilm  Using the GUI (Graphical User Interface) as shown.
