Fault Detection, Isolation, and Accommodation for LTI Systems Based on GIMC Structure

Journal of Control Science and Engineering, 2008
In this contribution, an active fault-tolerant scheme that achieves fault detection, isolation, and accommodation is developed for LTI systems. Faults and perturbations are considered as additive signals that modify the state or output equations.

Distributed Fault Detection and Isolation for Flocking in a Multi-robot System with Imperfect Communication

International Journal of Advanced Robotic Systems, 2014
In this paper, we focus on distributed fault detection and isolation (FDI) for a multi-robot system where multiple robots execute a flocking task. Firstly, we propose a fault detection method based on the local-information-exchange and sensor-measurement
