Investigation to Control Temperature and Humidity of Baby Incubator Using Fuzzy Logic

This paper deals with duty cycle control for baby incubator, the variables are temperature and humidity. Fuzzy logic provides a robust inference mechanism with no learning and adaptability. The result obtained shows that the fuzzy logic control is a digital control technique for non linear applications and it offers a very fast and accurate control. Further it is observed that chattering is removed as the 'on' time with fuzzy logic control remains nearly constant. Further, the disadvantage of manual control, relay control and other conventional control techniques have been removed in fuzzy logic based duty cycle control.
