摘　　要：针对船用锅炉汽包水位控制的特点,提出将阶梯式广义预测策略应用于船用饱和蒸汽辅锅炉汽包水位控制。仿真研究表明,该策略的控制效果优于常规的PID控制,它能适应对象参数的变化,具有较强的鲁棒性和自适应能力。In view of the characteristics of water control in the marine boiler steam drum, the step generalized predictive control method was proposed to control the water level system of the marine saturated steam auxiliary boiler steam drum. The simulation result showed that the control effect by this step control strategy is superior to that of normal PID control with strong robustness and self-adaptability, and can readily accommodate itself to the object＇s parameter variations.
