摘要
对循环流化床机组的主汽压控制系统进行了分析,并设计了一个先进PID控制器。它的特点是将PID控制与模糊控制相结合,在PID控制的基础上,用模糊推理的方法对PID进行调节。仿真结果表明:模糊控制器对其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等复杂过程的控制。
This paper expounds the main steam pressure control system of circulating fluidized bed. It suggests a fuzzy controller and it has been simulated. Simulation results show the fuzzy controller has better control characteristics. So this controller has better availability for engineering implementation.
