摘要
电厂循环流化床锅炉的正常运行受到很多因素的影响,因此使其在实现自动控制方面遇到困难。根据循环流化床锅炉的特点,将自适应理论与模糊控制相结合,设计了一种基于BP神经网解耦的具有参数在线自调整功能的自适应模糊控制器,并应用于循环流化床锅炉燃烧控制系统中。该控制器不但可以适应被控对象的变参数运行工况,而且可以实现循环流化床锅炉燃烧过程主汽压力与床层温度的解耦控制。仿真试验和现场应用结果证明,本控制器对循环流化床锅炉燃烧过程具有良好的控制效果。
The operation of circulating fluidized bed boiler in power plant can be disturbed by many factors;it is difficult to realize boiler automatic control.Based on the characteristic of circulating fluidized bed boiler(CFBB),an adaptive fuzzy controller was designed and applied in the control of CFBB combustion system,which has the function of self-adjusting.The controller can not only adjust parameters on line but also realize the decoupling of main steam pressure and bed temperature.Simulation test and field application results show that the controller has excellent control effect for CFBB combustion process.
