某型飞航导弹的三维模糊控制器

为解决传统控制方法难以实现或难以奏效的控制问题,设计三维模糊控制器。介绍三维模糊控制器的设计方案,通过选择描述输入输出变量的词集、确定语言值的隶属度函数、制定模糊控制规则表、对Ke、Kec和Ku进行设计,并以涡喷发动机为动力装置的导弹偏航通道为例,采用分段控制策略进行实验分析。结果表明,三维模糊控制器能提高系统的响应速度,基本上实现无超调控制,系统的跟踪性能也得到明显改善,满足系统的性能指标要求。

Three-Dimensional Fuzzy Controller for a Certain Type Guided Missile

In order to solving traditional controlling problems of being difficult in performance,a three-dimensional fuzzy controller is designed.Introduce the design scheme and designing Ke,Kec and Ku based on choosing expression variables in and out,ensure subjection function of language values and establishing rule table of fuzzy control.A three-dimensional fuzzy controller applied to aerodynamics missile system is designed,which adopted the strategy of subsection control.The results of simulation demonstrate that the controller has such advantages as quick response and no over adjusting control.The track ability of the system is still improved,and the controller reaches the request of the system performance indexes.
