模糊控制与特征结构配置方法在飞行控制律设计中的应用

Application of Eigenstructure Assignment and Fuzzy Control Method to Design of Flight Control System

将特征结构配置与模糊控制理论相结合对飞机侧向偏离控制律进行设计。首先介绍了特征结构配置的原理和反馈增益矩阵的算法,在此基础上结合带优化修正函数的无量化模糊控制规则自调整方法对闭环系统进行鲁棒控制器设计。该控制策略以特征结构配置作为内环控制器,模糊控制器作为外环控制器,使控制系统具有较好的动态性能和较强的鲁棒性。仿真结果表明系统获得了较好的动态性能,并且有效抑制了内部参数摄动对系统的不良影响。

The paper presents a design technique using eigenstructure assignment and fuzzy controller for FCS.Eigen- structure assignment can satisfy specifications in terms of dynamic response,while fuzzy controller ensures good robust performance of closed-loop system.The simulation results show that the designed system based on eigenstructure as- signment and fuzzy controller has good dynamic qualities and the ability of parameter disturbance rejection.
