Presentation Transcript

  1. Fuzzy Control

  2. Fuzzy Control • Fuzzy Sets • Design of a Fuzzy Controller • Fuzzification of inputs: get_inputs() • Fuzzy Inference • Processing the Rules: find_rules() • Centroid Defuzzification • Output Defuzzification: find_output() • A Fuzzy Control Example -- • Floating Ping-Pong Ball

  3. Fuzzy Logic

  4. Fuzzy Sets Is this sentence true or false?

  5. Probabiltiy vs. Fuzziness Probability describes the uncertainty of an event occurrence. Fuzziness describes event ambiguity. Whether an event occurs is RANDOM. To what degree it occurs is FUZZY.

  6. Probability: There is a 50% chance of an apple being in the refrigerator. Fuzzy:There is a half an apple in therefrigerator.

  7. Fuzzy logic acknowledges and exploits the tolerance for uncertainty and imprecision.
