智能控制在锅炉过热汽温控制中的应用研究

电站锅炉过热蒸汽温度具有较大的非线性及较强的耦合性，用传统的PID串级系统进行控制，通常难以达到理想的控制效果。将模糊控制与常规的串级系统结合起来，将其应用于某300MW燃煤单元机组的过热器出口蒸汽温度的控制．进行了仿真研究。通过与常规串级系统、单纯的模糊控制系统以及Fuzzy-PI控制系统的比较，仿真结果说明这种复合控制方法对大延迟、大惯性、非线性对象具有很好的控制效果：

A New Control Method to Superheated Steam Temperature of Power Station Boiler

To the bad nonlinearity and coupling of the power station boiler superheated stean temperature,It is very difficult to gain excellent control with the traditional PID cascade method and the. The combined fuzzy and traditional cascade PID system was applyed to the 300 MW unit coal-fired power plant's steam temperature control, The simulation results verify the effectivenes and practical value of the cascade fuzzy control method to the big delay,big inertia and nonlinear object.
