摘要
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 ,很难建立被控对象准确的数学模型 ,因此难以实现常规方法的控制。本文设计了一个模糊控制器并进行了仿真研究 ,仿真结果表明模糊控制器对本文控制对象具有良好的控制性能 ,该控制方法可用于流化床锅炉燃烧系统这类复杂过程的控制。
Circulated Fluidized Bed (CFB) Boiler has been developed quickly for its higher efficiency, lower pollution and lower cost. But because of the complexity of its combustion, it is difficult to build the exact math model of controlled object. So it makes the traditional control method almost impossible. In this paper it suggests a Fuzzy Controller and it has been simulated. Simulating results show the Fuzzy Controller has better control characteristics. So this controller has better successful availability for engineering implementation.
