1 A fuzzy control system that describes a vehicle's stopping distance has the following rule base Rule 1:1F speed is fast OR road condition is slippery, THEN stopping distance is speed + road condition. Rule 2: IF speed is medium AND road condition is normal, THEN stopping distance is 50. Rule 3: IF speed is slow, THEN stopping distance is speed. Figure 2 shows the membership functions for the input variables 'speed' and froad condition', respectively. 1 slow medium fast INA 0.5 엉 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 speed (miles per hour) 1_slippery normal 0.5 0 0 1 2 5 6 7 3 4 road condition Figure 2 (a) (b) ) Which type of fuzzy inference system (FIS) is this system. Justify your answer clearly. Name the other type and describe the main advantage and disadvantage of adopting this type. (10 marks) Assume that the speed is 40 miles per hour and the road condition is 3. Evaluate the truth degree of the three rules given in the question. Calculate the output stopping distance of each rule. Calculate the overall output stopping distance from the system. Show your work clearly. 0 (iii)
