摘　　要：根据锅炉汽包水位控制的工艺要求 ,以汽包水位双冲量、三冲量控制方案为例 ,对被控对象的实际构成进行了对象特性和干扰因素的定位定性分析。In accordance with the technique requirement for water level control of boiler drum, with drum water level two element and three element control strategy as example, the characteristic of object and disturbance factors are analyzed qualitatively and orientationally. This will be a theoretical guidance and valuable reference for selecting proper control strategy of drum water level.
