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) Find the crisp z*, when the room temp. is 30C, and the outside temp. is 20C. Find the crisp z*, when the room temp. is 20C, and the outside temp. is 40C.
