摘　　要：根据密闭输油的工艺要求,提出了双PID控制器控制一个出站调节阀的方法。理论分析并给出了PID控制器自动/手动无扰动切换的条件,然后通过对上位机与下位机编程,实现了滨州站调节阀控制器自动/手动的无扰动切换、远控/现场手动的无扰动切换。该方法同时实现了调节阀的自动PID控制、手动站控、现场手动控制三种控制方式。实践证明该方法非常成功。According to the technics requirement of custody transfer, the article put forward the method of two PIDcontroller controlling one adjustment valve. The article analyze in theory and implement the condition ofbumpless transfer of PID controller. And then basing on computer and PLC programming, bumpless transferof adjustment valve is realized. At the same time, the method also realize automatic PID control ,manualcontrol in station and local manual control. The method is used successfully in BINZHOU station.
