Electric control system of inverter air-conditioning based on fuzzy control

摘要

Fuzzy controller of temperature was designed in the inverter air-condition with dual purpose both cold and hot. The control system of inverter air conditioner was divided two parts, that is, indoor machine and the outdoor machine. The frequency control of indoor and outside machine was realized by control software in the foundation of hardware circuit design. Fuzzy control program was selected, two-dimensional temperature controller was designed. PID fuzzy controller suitable for real-time control was proposed in this paper. Finally, the practicability of self-adjust PID fuzzy controller was confirmed by simulation curve. It was shown that self-adjust PID fuzzy controller had a better control performance than conventional fuzzy control methods.
