Faults Modeling in Networked Environment and Its Tolerant Control with Multiple Simultaneous Faults

Mathematics, 2023
This paper presents two new fault models for networked systems. These fault models are more realistic and generalized for networked systems in the sense that they can represent the effects of fault at the node and network levels.

Variation-aware fault modeling [PDF]

Science China Information Sciences, 2010
To achieve a high product quality for nano-scale systems both realistic defect mechanisms and process variations must be taken into account. While existing approaches for variation-aware digital testing either restrict themselves to special classes of defects or assume given probability distributions to model variabilities, the proposed approach ...

Logical Physical Synthetically Modeling Method Based on Fault Diagnosis in Electrical System [PDF]

Jisuanji gongcheng, 2017
The fault diagnosis method based on modeling is intuitional,reconfigurable and also effective.However,modeling the signal/function of electrical system can hardly locate the physical position of the fault.Therefore,this paper expands Logical Physical ...

Robust Fault Detection Based on l1 Regularization

Advanced Intelligent Systems, 2021
Herein, l1 regularization‐based fault detection technique for stochastic discrete time systems in state space form is discussed. Compared with the deterministic nature of a fault which usually causes an abrupt change, the state of a system smoothly ...
