模糊控制在循环流化床锅炉床层温度控制中的应用

The application of fuzzy control to the bed temperature control system of circulated fluidized-bed boilers

近年来循环流化床锅炉因其高效、低污染、低成本等特点得到了迅速的发展 ,但由于其燃烧过程十分复杂 ,很难用准确的数学模型来描述 ,因此难于实现常规方法的控制。本文设计了一个带自调整因子的模糊控制器并进行了仿真研究 ,仿真结果表明该控制器具有良好的控制性能 ,有望用于流化床锅炉燃烧系统这类复杂过程的控制。

The circulated fluidized bed boiler(CFB) has been developed quickly for its high pollution and low cost. But because of the complexity of its combustion, it is difficult to build an exact math model for a controlled object. So it is hard to perform control with traditional techniques. This paper presents a fuzzy controller with a self adjusting factor and its simulating research. The simulated results show that the controller has good control performance. It is hopeful for such a controller to be used in a complicated combustion control system for the circulated fluidized bed boiler.
