3. For a discrete fuzzy control system with the following fuzzy rule-base, both of the representative values of a room temperature 'x' and an outside temperature 'y' are [0 10 20 30 40 50] C, and the representative cooling motor current 'z' is [0 1.0 2.0 3.0] amperes. Use the simplified method of fuzzy inference engine in order to obtain the crisp motor current 'z*'. (Use the "fis" data structure in Matlab or similar one in Python Libraries) 1) Find the crisp z*, when the room temp. is 30C, and the outside temp. is 20C. 2) Find the crisp z*, when the room temp. is 20C, and the outside temp. is 40C. RULE1: IF (x is HIGH [0 0.1 0.3 0.5 0.7 1]) AND (y is LOW [1 0.7 0.5 0.3 0.1 0]) THEN (z is MEDIUM [z = 2.0 (A)]) RULE2: IF (x is HIGH [0 0.1 0.3 0.5 0.7 1]) AND (y is HIGH [0 0.1 0.3 0.5 0.7 1]) THEN (z is FAST [z = 4.0 (A)]) RULE3: IF (x is LOW [1 0.7 0.5 0.3 0.1 0]) AND (y is LOW [1 0.7 0.5 0.3 0.1 0]) THEN (z is STOP [z = 0 (A)])
