Intelligent Environment Systems M. F. for IP & OP with trimf & guass

Intelligent Environment Systems q Similarly built other MF relationships for inputs and outputs in guassian curves and triangular MFs. q Inputs : Inside Temperature, Outside Temperature, Season, Time of the Day, Specific Heat of Air and Humidity. q 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. q Graphical: Use the rule viewer to shift input parameters as desired and corresponding output parameters are changed q Using C code: A = readfis (‘greenhouse’) Out = evalfis ([time otemp hum seas intemp spair], A) That is Out = evalfis ([3 40 40 4 40 6], A) Out = 5. 00 2. 00 5. 00 vent heat light soilm q Using the GUI (Graphical User Interface) as shown.
