Fault identification for robot manipulators
IEEE Transactions on Robotics, 2005Several factors must be considered for robotic task execution in the presence of a fault, including: detection, identification, and accommodation for the fault. In this paper, a nonlinear observer is used to identify a class of actuator faults once the fault has been detected by some other method.

Fault identification and accommodation for incipient and abrupt faults
2007 46th IEEE Conference on Decision and Control, 2007This paper proposes a fault tolerant control strategy for failures belonging to a class of functions including both incipient and abrupt faults. To this purpose a sliding mode controller has been designed ensuring the robust boundedness of system trajectories.

On Fault Identification in Diagnosable Systems
IEEE Transactions on Computers, 1981This paper begins by giving a characterization of t1/ t1—diagnosable systems. Then a class of t0-diagnosable systems, denoted by d(n,t0,X), is considered. It is shown for any member of this class that: 1) necessary and sufficient conditions for t1/t1—diagnosability are greatly simplified, 2) optimal diagnosis algorithms of time complexity 0(nt0) exist,

On-line identification of faults in fault-tolerant imagers
20th IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems (DFT'05), 2006Detection of defective pixels that develop on-line is a vital part of fault tolerant schemes for repairing imagers during operation. This paper presents a new algorithm for the identification of stuck low, stuck high and partially stuck pixels in both regular and fault tolerant APS systems.
