【摘要】 在对水轮机调速器的模糊控制研究中,很多文献采用的是多条模糊控制规则,但由于参数整定复杂未能取得满意的效果,为此推荐采用PI型模糊控制器。PI型模糊控制器采用变宽度的隶属函数,只需建立偏差模糊控制规则库,不考虑偏差变化率,从而使计算时间大为缩短,而且既能消除静差,又具有抗负荷干扰的能力。经仿真实验表明,PI型模糊控制器比常规的PID控制及一般的模糊控制具有更良好的动、静态性能和鲁棒性,且节省计算时间、简单有效。更多还原

【Abstract】 In the research of fuzzy control for governor of turbine,more than one fuzzy control rules are used in some references.Because the parameters are difficult to selection,satisfied results could not obtained.We have,therefore,suggested adopting fuzzy controller PI.Belonging function with variable width is adopted in the fuzzy controller.It only needs to establish a deviation fuzzy control rule base,and variety rate of deviation needn’t be considered.The controller has some advantages such as greatly shortening calculation time,dissolving the static deviation,and etc.Simulation test elucidated that fuzzy controller PI had better dynamic and static properties,more anti-interference property,shorter calculating time than conventional controller PID.更多还原
