船用锅炉汽包水位模糊控制研究

传统的锅炉汽包水位单回路PID控制方案,无法克服汽包蒸汽流量扰动的影响。文章提出带模糊监督的控制方案,扰动经模糊处理后作为前馈控制信号,通过引入监督控制环节自动调整前馈控制和反馈控制的权重,以实现控制目标。以船用锅炉汽包水位控制为对象,采用上述控制方法实现锅炉汽包水位的模糊双冲量控制。经计算机和热态仿真,表明系统超调量较小,有较好的有效性和实用性,证明所采用的控制方案是可行的。

Research on the Fuzzy Controller of Marine Boiler Drum Level

For classical single loop PID control on marine boiler drum level, the disturbance of steam flux can't be solved. A new fuzzy control with fuzzy supervisor method is put forward, in this method, the fuzzy feed-forward control is applied to transact the impact of measurable disturbance signal, and the fuzzy supervisor is used to adjust the proportion of feed-forward control and feed-back control automatically, the control purpose is carried out .Using this method, the double impulse fuzzy control of a marine...
