摘要
研究了导弹竖直平面动力学LPV模型的故障检测和隔离滤波器的设计问题.LPV故障检测滤波器利用几何控制的概念,是基于线性时不变系统的故障检测滤波器的扩展.建立了用于LPV故障检测滤波器设计的导弹模型以及导弹舵机执行器和角速度传感器的故障模型,在此基础上设计了一组FDI滤波器来检测和隔离这些故障.仿真结果验证了这组FDI滤波器的有效性.
The fault detection and isolation(FDI) filter design problem for a linear parameter varying(LPV) model of the longitudinal dynamics of a missile is studied.Motivated by some geometrical control concepts,the LPV FDI filter is an extension of FDI filter for linear time invariant(LTI) systems.The model of a missile for LPV FDI detection filter and the fault models of missile tail actuators and pitch rate sensors are established.Based on them, a bank of LPV FDI filters is designed to detect and isolate these fa...
