Microcontroller-Based Energy Saving Control for Air - Conditioning System Using Fuzzy Logic Approaching: An Overview

Energy consumption for room air-conditioning accounts for about half of the total energy used in the building equipment area. Under this situation, it is clear that a major contribution to energy saving can be made by achieving greater energy efficiency if the air-conditioning systems is controlled more effectively such as controlled by a 68HC12 microcontroller system using fuzzy logic approaching. With energy efficiency concept adapt to the institution power demand, great savings can be archived. Fuzzy control has been widely applied for handling the system which has uncertainty or high robust system. Since the dynamic behaviors of the systems contain complexity and uncertainty in its parameters, several fuzzy logic controllers have been implemented to control room temperature in the field of air-conditioning system. This paper describe the MC68HC12 microcontroller features that support Fuzzy Logic, introduces Fuzzy Logic and intelligent control. The goals of these studies are to illustrate Fuzzy Logic theory, to apply Fuzzy Logic features of the MC68HC12, and to implement applications of fuzzy control for air-conditioning system.
