基于tdofmdpid的循环流化床锅炉主蒸汽压力控制系统研究
, PP. 94-97
Keywords: cfb锅炉,主蒸汽压力,tdofmdpid控制器,常规pid控制器,燃料量
Abstract:
针对循环流化床（cfb）锅炉燃烧系统所具有的大延迟、大滞后等特性，以主蒸汽压力为被控对象，基于常规pid控制系统，设计了二自由度的模型驱动pid（tdofmdpid）控制器，分析了燃料量对主蒸汽压力的影响特性。通过仿真试验对tdofmdpid控制器与常规pid控制器的控制性能进行了对比。结果表明，tdofmdpid控制器结构简单，参数易于调整，具有很强的鲁棒性和抗干扰性，能够有效地改善控制系统的动态品质。
