A Thermostat Fuzzy Control System Based on MCU

A thermostat is an automatic temperature control unit, which operating environment is featuring by non-linear, inertial and time-variant. Traditional control can not achieve satisfied performance. As one large embranchment of non-linear control, fuzzy control can manage it better. This paper presents a thermostat intelligent control system with fuzzy algorithm, which constructed on Samsung SAM8 MCU platform. Both hardware and software design is given; experimental result shows that this control system has outstanding tracking performance, small overshoot quantity and short response time.
