This brief is concerned with the problem of nonlinear fault detection, isolation, and recovery (FDIR) for the satellite's orbital and attitude models through construction of residual generators that are based on least-squares parameter estimation techniques. By viewing system anomalies caused by faults and/or malfunctions as changes of certain parameters in the system, our goal is to detect, isolate,...
In this paper, the problem of actuator fault detection and isolation (FDI) for almost-lighter-than-air-vehicles (ALTAVs) is investigated using a nonlinear geometric approach. Due to the particular dynamics of the ALTAV, six detection filters are designed for FDI of the four input channels of the ALTAV. Four of the detection filters are designed such that each input channel affects only one of the...
In this paper, aircraft actuator fault detection and isolation (FDI) is investigated and designed using a nonlinear geometric FDI approach based on a nonlinear longitudinal aircraft model. Two detection filters are designed for the throttle position and the elevator angle, respectively, which are the two main actuation signals in the longitudinal aircraft model. In nonlinear geometric FDI approach...
