Simultaneous Actuator and Sensor Fault Isolation of Nonlinear Systems Subject to Uncertainty

This work considers the problem of actuator and sensor fault isolation for nonlinear systems subject to uncertainty. The key idea is to detect and isolate faults by using a bank of filters, dedicated to each fault that captures the difference between the observed and expected behavior of system while allowing thresholds, cognizant of the uncertainty. To this end, high gain observer are first designed and the bounds on the estimation error, …
