This work considers the problem of designing an active fault isolation scheme for nonlinear systems subject to uncertainty. The key idea is to utilize the control action to drive the system to a region which allows isolation of faults not otherwise possible under nominal operation. To this end, dedicated residuals are generated for the faults under consideration. To make these residuals sufficiently...
In this work, we consider the problem of designing an integrated fault diagnosis and fault‐handling framework to deal with actuator faults in nonlinear systems. A model‐based fault diagnosis design is first proposed, which can not only identify the failed actuator but also estimate the fault magnitude. The fault information is obtained by estimating the outputs of the actuators and comparing them...
