| 摘 要： | 为了解决多传感器故障检测与隔离这一难题,建立了包含卡死、增益时变和偏差时变等三种典型传感器故障的数学模型.借助输出方程,将待检测的传感器故障转换到系统状态方程中进行处理.设计出既能检测出故障,又能将各个故障进行有效隔离的残差产生器,同时还要给出设计残差产生器过程中未知参数的求解方法.用算例对上述设计结果的有效性进行计算...

| Abstract: | In order to solve the problem of multi-sensor fault detection and isolation,a unified fault model for lock-in-place,gain time-varying and bias time-varying is established.We resort the output equation to converted sensor fault into state disturbance of the dynamic system.A residual generator which can well be used to fault detection and isolation is designed.In addition,we also put forward the method of solving unknown parameters in it.The effectiveness of this method is verified through example simulation. |
