This work considers the problem of fault detection and isolation (FDI) and fault-handling for networked systems subject to actuator faults. The faults considered preclude the possibility of nominal operation in the affected unit. First, a model-based methodology is presented to detect and isolate faults with the explicit consideration of uncertainty. Then, an algorithm is developed to generalize the safe-parking approach for fault-tolerant control to account for complex interconnections such as parallel and recycle structures in networked systems. The efficacy of the integrated FDI and safe-parking framework is demonstrated through a chemical process example.
