This paper presents unknown-input observer-based approach for robust fault detection and isolation of a class of nonlinear Lipschitz systems subject to unknown inputs or disturbances. Residual signals are generated by bank of observers to detect and isolate between actuator faults and sensor faults. The effect of unknown inputs or disturbances can be… (More)
