| 摘 要： | 针对一类仿射非线性飞行控制系统的执行器故障,提出了一种基于微分几何方法的鲁棒故障诊断方案.各个输入通道相应的不可观分布满足条件时,可以通过分别在状态空间和输出空间进行同胚变换,将原系统化为多个只受单一通道故障输入影响的能观商子系统.原系统的残差生成器设计问题转化为对其各通道能观商子系统的观测器设计,实现残差与其他通道故...

| Abstract: | A robust fault diagnosis approach based on differential geometric is proposed for a class of affine nonlinear flight control systems with actuator faults.For the case that the corresponding unobserverability distribution to each input channel exists,by the state and output space diffeomorphism,the original system is transformed into observable quotient subsystems affected by only one fault signal.The residual generator problem of original system reduced to the design of observers for observable quotient sub... |
