Conventional microwave ovens rely on users for their cooking time. In other words,
the user must set the oven’s cooking time manually. This paper aims to design a fuzzy logicbased
controller to resolve the above-mentioned issue by determining the cooking time of the
microwave oven automatically. The time determined depends on the quantity and type of food.
During the fuzzy logic process, we used the Mamdani fuzzy model. This model involves
determining the crisp input, fuzzification, rule evaluation, and defuzzification, to obtain the
crisp output result. Input real variables used were the type of food and quantity of food,
whereas the output variable used was cooking time. A fuzzy logic toolbox on MATLAB
software was used to design and simulate the whole system. Considering the IF-THEN rules and functions, we used the value of food as 50, and the type of food as 50 and we obtained the cooking time as 25 minutes. The result showed that Fuzzy models are good at determining
cooking time in Microwave ovens and that their cooking time depends on the inputs. Using
fuzzy logic in microwave ovens helps to maintain food quality, saves users’ time, and controls
the energy used by the ove
