Application of parameter self-adaptive fussy PID control in central air-condition saving-energy system

The problem about energy consumed by central air-condition is paid attention by people. There are great non-linearity, lag and variety of parameter in this system. Traditional PID control arithmetic has some difficulty. The merit of fussy-control is that there is better dynamic response characteristic. The mathematic model is not needed in this arithmetic. There is better adaptability, faster rise time and better robust characteristic. But there is error in fussy-control by limited grade. So we use AT89C58 as control kernel and use fussy-PID arithmetic in this system. It ensures that there is faster, more stability and smaller error. This control system has been proved stable by some experiment, the anti-interference ability is strong. It can satisfy completely the need of variable-flux equip.
