在某船舶原蒸汽动力装置废汽总管压力控制系统基础上,综合运用前馈控制、专家控制和自适应控制,提出了一种改进的方案并应用于实船。通过改进前后运行数据的对比,表明了改进后的废汽总管压力控制系统能够更好地适应控制过程中外来扰动对系统的影响。废气总管压力在除氧器蒸汽流量扰动下调节时间由60 s缩短至36 s。改进后的系统响应更迅速、超调量更小、更稳定。 Based on the pressure control system of the waste steam main of the original steam power plant of a ship, an improved scheme is put forward and applied to the real ship by comprehensively using feedforward control, expert control and adaptive control. By comparing the data before and after operation, it is shown that the improved control system of waste gas header can better adapt to the influence of external disturbances on the system. The exhaust manifold pressure was reduced from 60 s to 36 s with deaerator steam flow perturbation. Improved system response more quickly, overshoot smaller, more stable.
