摘　　要：锅炉汽包水位预测与控制是锅炉运行安全的保证。目前研究预测与控制主要采用统计学相关原理与算法,主要对给水流量、蒸汽流量等参数进行单独研究。通过这些方法提高了汽包水位预测准确性,降低控制反应延迟时间,但需要对相关影响参数进行协同影响研究,使汽包水位的影响因素之间的相互作用及共同作用于汽包水位更具有实际意义。The boiler steam drum water level prediction and control has been a guarantee for safe operation of the boiler, the present the statistical forecast and control related principle and algorithm mainly used. The main parameters such as feed water flow and steam flow for individual study, through the steam drum water level of these methods can improve the prediction accuracy, reduce the control response delay time, but related parameters affecting the synergy effect were needed to research, the interaction between the influence factors of the steam drum water level and work together in the steam drum water level has more practical meaning.
