Isolation and handling of sensor faults in nonlinear systems

This work considers the problem of sensor fault detection and isolation (FDI) and fault-tolerant control for nonlinear systems subject to input constraints. The key idea of the proposed method is to exploit model-based sensor redundancy through state observer design. To this end, an output feedback control design using high-gain observers is first presented. An FDI scheme that utilizes the enhanced applicability of the observer design is then …
