  1. IMAT3406 Fuzzy LogicWeek 10 Fuzzy Logic Applications

  2. Fuzzy Logic Applications Digital Fuzzy Processor Omron was the first to launch a controller employing fuzzy logic for improved control and tuning Production of the world's fastest digital fuzzy processor (DFP) in 1990. Reasoning speed of 10 MFLIPS (1 Million Fuzzy Logic Inferences per second)

  3. Input Variables for Fuzzy Logic Traffic Signal Controller Maximum Queue Length (in metres): the distance in metres from the stop-line over which vehicles have queued Average Occupancy Rate (%): percentage of time that the detection area was occupied by one or more vehicles. Output Variable for the Controller Weight[0, 100]: the degree of green traffic signal requirement Applications of Fuzzy Logic to Traffic Signal Control (Budi Yulianto, “Application of fuzzy logic to traffic signal control under mixed traffic conditions”, tec, October 2003, pp:332-335) Improvement (up to) 25% in average travel time

  4. # of rules : 16

  5. Rule Table/Matrix for Traffic Signal Control Maximum Queue Length Average Occupancy Rate L: Low, VL: Very Low, VVL: Very Very Low, M: Medium, H: High, VH: Very High, VVH: Very Very High

  12. Gene identification and gene network modelling List of genes associated with diseases/condition Fuzzy System Gene networks

  13. Fuzzy Logic Applications in MATLAB • You can see a list of the applications in Fuzzy Logic Toolbox’s Demo. You will be shown a couple of them in the lecture. However, you are advised to go through all the applications provided in the toolbox’s demo • They can be found at Help/Full Product Family Help/Demos/Toolboxes/Fuzzy Logic
