An identification scheme for robot actuator faults [PDF]

2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005
We present a scheme for identifying the time profile of actuator faults that may affect a robot manipulator. Starting from our previous method for fault detection and isolation (FDI) based on generalized momenta, fault identification is additionally obtained through the H/sub /spl infin//-design of a state observer for uncertain systems.

Transmission line fault identification method based on weighted federated learning and multimodal residual network

International Journal of Electrical Power & Energy Systems
Although data-driven deep learning networks can be used for transmission line fault identification, the generalization performance of the algorithm will be seriously reduced in the face of “data islands” and class imbalance among fault samples in various
