Fuzzy Logic Controller Deployed for Indoor Room Temperature Control

Abstract

Fuzzy logic is widely used in machine control. Although genetic algorithms and neural networks can perform just as well as fuzzy logic in many cases, fuzzy logic has the advantage that the solution to the problem can be cast in terms that human operators can understand, so that the experience can be used in the design of the controller. In this system, distributed temperature sensors are used inside the room to measure inputs to the fuzzy system. Sensors’ signals are taken as inputs to the microcontroller in fuzzification process. PIC16F877 microcontroller is used to control the system. The controller output can decide the fan operation.
