摘要
通过建立球阀角度与过流面积非线性关系,解决PID过程控制球阀角度时引入的周期干扰,在CO2热泵的水温控制中获得较好控制效果。
Through establishing non-linear relationship between valve angle and flow area,the cycle interference in the process of PID controlling valve angle is resolved.It obtains the better control effect in the water temperature control of CO2 heat pump.
