1. Fuzzy Logic What is that? Prof. Dr. T. Nouri Nouri@acm.org

2. Fuzzy Sets 1-2

3. Fuzzy Sets 2-2

4. SpeedDistance Brake Example: Fuzzy Driving

5. Fuzzy Processing Unit, FPU

6. Input Fuzzy Set : Distance

7. Input Fuzzy Set : Speed

8. Knowledge-Base

9. Rule 2: If Distance is Low and Speed is High Then Brake is High Etc. Rule 1: If Distance is Middle and Speed is High Then Brake is Mittel

10. Output Fuzzy Set: Brake

11. Facts: Distance = 35 m Speed = 90 Km/h

12. Distance = 35 m, LowSpeed = 90 km/h, High

13. Result of Rule 1Result of Rule 2 Addition of Two Fuzzy Sets

14. Defuzification Center of Gravity 71% of Brake Intensity

15. Deffuzification The Output Fuzzy Set is converted into Discret (Crisp) Value. Center of Gravity Method is the most used to make this conversion
