摘要: 为了实现对蒸汽发生器水位的有效控制,设计了双级模糊积分智能水位控制器。在常规模糊控制器之前,增加了“假水位”判别模糊控制器,以实现在“假水位”阶段对水位进行有效控制。为实现对水位的最优控制,将模糊控制器和积分控制器结果协调输出。通过对控制响应曲线的分析,验证本论文所设计的双级模糊积分智能控制器能有效克服“假水位”现象对水位控制带来的不利影响,且控制超调量小,稳定时间短。Abstract: In order to effectively control the water level of steam generator,a double-fuzzy-integral-water level controller is designed in this paper.A “false water level” distinguishing fuzzy controller is added-before normal fuzzy controller,to control the water level effectively when SG is in “false water level” phase.In order to have an optimal water level control,this paper gives the result of fuzzy controller and integral-controller export in phase.By the analyzing of control curve,it has validated that the designed double-fuzzy-integral water level controller may overcome the disadvantageous influence given by “false-water level” phenomena to the water level control,and that the control excess adjustment quantity is small and the steady time is short.
