摘　　要：对船用锅炉液位控制系统模型进行介绍,针对液位系统在给水扰动及蒸汽扰动作用下的响应分别进行分析。对一般锅炉的实际负荷情况,提出了基于变结构方法的液位控制方案,并应用于锅炉液位控制系统模型中。变结构控制方案的分析结论与液位控制常用的PID方案相比,具有响应快,过渡过程短,超调减少等优点,从而证明对锅炉液位控制系统而言本方案是可行的,有效的。This paper introduces the water level controlling system for marine boiler, and analysis the response owing to the disturbance of feeding water and steam demanding. For the general load of the marine boiler, we present a variable structure control （VSC） based method for water level control and applies it to the model of water controlling. Compared to the usual PID method, the method presented is proved to be fast response, short transition process, small over adjustment, and so on. And this method is practicable and efficient for marine water level controlling.
