[Solved] ECE 449 Assignment 4

1. A fuzzy system is used to control the temperature in a room. The inputs to the controller are the Temperature and Temperature change. The outputs are the Fan Speed and Heater power. The membership functions are shown in the following figures

and the rule base is described by the following table

If the temperature is 22 C and the change of temperature is 4 C/hr, answer the following questions: a) What is the result of fuzzification of those inputs?

1. Use the rules and Mamdani inference to specify the output fuzzy membership functions.
2. Calculate the Heater power and Fan speed using your choice of defuzzification method.
