摘要
针对舰船主锅炉燃烧控制系统负荷突变时主蒸汽压力波动大、空气和燃油调节速度慢以及风油配比易偏离最佳值的问题,在变偏置双交叉限幅燃烧控制系统的基础上,提出模糊-粒子群算法整定变偏置函数的偏置参数,制定大步长控制策略。在Simulink中建立模糊-粒子群控制器和燃烧控制系统模型,仿真试验结果表明:引入模糊-粒子群算法改进的燃烧控制系统主蒸汽压力超调量更小,调节时间更短,空燃比维持在良好范围内,可有效提升主锅炉燃烧控制系统的稳定性、快速性和经济性。
The controller design focuses on improving the response performance of ship main boiler control system when abrupt load change happens.It integrates a variable-bias double-crossing limiting combustion control system with a fuzzy-particle group algorithm for adjusting the bias parameters of the variable bias function and uses large step length control strategy.The system is simulated in Simulink,which shows that the controller achieves smaller overshoot,shorter regulating time and favorable air-fuel ratio.
