FDI飞机舵面损伤故障全局检测的非线性数学模型

阐述了飞机在单舵面损伤故障下 ,建立故障状态下的数学模型 ,以及同样输入条件下飞机正常运动时的数学模型 ,得到飞机在相同飞行条件下损伤时的气动系数和无损伤正常时的气动系数 ,最终得到气动系数的残差。这将为以后飞机过载残差和角加速度残差奠定基础。论文中结合一定的算例给予证实推论的正确性。

The Nonlinear Mathmatics Model of Globlely Detecting the Failure of Aircraft Rudder

This paper illustrates how to build the nonlinear mathmatics of failure status to get the failure aerodynamic coffient under the condition of single aircraft rudder failure and bulid normal flying mathmatics model in the same input condition to get the normal aerodynamic coffient,finally aerodynamic error difference is gainde which establishs the base for aircraft load error and angular acceleration error.It is confirmed to be true by certain example.
