Adaptive Fault-Tolerant Control of Wheeled Mobile Robots With Multiple Actuator Faults and Saturation

RA-L 2025

The actuator fault problems under saturation bring significant challenges to the stable and accurate tracking of wheeled mobile robots (WMRs) in industrial applications. This letter proposes a novel adaptive fault-tolerant control (FTC) method for WMR systems simultaneously considering uncertain mul

Improving Transferability of Adversarial Examples with Virtual Step and Auxiliary Gradients

IJCAI 2022poster

Deep neural networks have been demonstrated to be vulnerable to adversarial examples, which fool networks by adding human-imperceptible perturbations to benign examples. At present, the practical transfer-based black-box attacks are attracting significant attention. However, most existing transfer-b…
