Sensor-fault detection and isolation using interval observers [PDF]
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013 This paper proposes an interval observer-based sensor fault detection and isolation (FDI) approach for the closed-loop systems. In this proposed approach, residuals are defined in such a way that their components are independent of each other at the time instant after fault occurrence, namely kf + 1, where kf denotes the fault occurrence time instant ...

Redundant ADS and INS High Sensitivity Fault Detection Method
Xibei Gongye Daxue Xuebao, 2020 The fault detection function of GLT method is approximately proportional to the square of fault value, the value of the fault detection function is lower than the detection threshold when the soft fault is small, which leads to the low sensitivity of ...
