摘要

针对舰用蒸汽动力系统工况转换中主蒸汽压力调节过程波动幅度大、稳定耗时长等问题，提出一种PID和隐式广义预测控制复合的控制方法。建立包含增压锅炉、主汽轮机、冷凝器等设备的蒸汽动力系统仿真模型，并通过实验数据进行校验；采用PID-GPC隐式控制方式对仿真模型进行升降负荷实验。结果表明：PID-GPC隐式控制方法弥补了GPC隐式算法初次响应慢的缺陷，减小了动态变化过程中主蒸汽压力波动幅度，缩短稳定时间。

Abstract

Considering the influence that the great fluctuation amplitude and stabilization time of the main steam pressure

a comprehensive control method combining implicit GPC and PID was proposed. The model of the steam power system were built

including supercharged boiler

main steam turbine and condenser. The simulation system was validated through the experimental data. The simulation test was took on the models with the PID-GPC implicit algorithm. The results shows that the control strategy of the PID-GPC implicit algorithm makes up for deficiencies of the poor initial response of implicit GPC

reduces the fluctuation amplitude of the main steam pressure during the dynamic process

shorten the settling time.
