Design of A Room Temperature And Humidity Controller Using Fuzzy Logic

چکیده
This research paper describes the design of a room temperature and humidity controller using fuzzy logic. The proposed model consists of two fuzzy logic controllers to control temperature and humidity respectively. The first controller accepts two input valuesthe current temperature as detected by temperature sensor and its deviation from user set-temperature, and controls the speed of heat-fan and cool-fan accordingly . When the current temperature in the room reaches set point, it serves as one of the input for second fuzzy logic controller that controls the humidity. The ideal relative humidity level for user’s set temperature is preset in the system. Current humidity in % as detected by the humidity sensor in the room serves as the second input to the controller. The humidifier and exhaust fan speed is controlled accordingly to maintain the correct humidity level for that temperature. This research work will increase the capability of fuzzy logic control systems in process automation with potential benefits. MATLAB-simulation is used to achieve the designed goal.
