A study on fault diagnosis in nonlinear dynamic systems with uncertainties

no code implementations6 Sep 2023 Steven X. Ding, Linlin Li

It is demonstrated that the projection onto the manifold of uncertainty data, together with the correspondingly defined Bregman divergence, is also capable for fault detection.

Replay Attack Detection Based on Parity Space Method for Cyber-Physical Systems

no code implementations3 Jun 2023 Dong Zhao, Yang Shi, Steven X. Ding, Yueyang Li, Fangzhou Fu

The replay attack detection problem is studied from a new perspective based on parity space method in this paper.

Control theoretically explainable application of autoencoder methods to fault detection in nonlinear dynamic systems

no code implementations2 Aug 2022 Linlin Li, Steven X. Ding, Ketian Liang, Zhiwen Chen, Ting Xue

The major efforts are made on the development of a control theoretic solution to the optimal fault detection problem, in which an analog concept to minimal sufficient statistic, the so-called lossless information compression, is introduced and proven for dynamic systems and fault detection specifications.

An alternative paradigm of fault diagnosis in dynamic systems: orthogonal projection-based methods

no code implementations16 Feb 2022 Steven X. Ding, Linlin Li, Tianyu Liu

In this paper, we propose a new paradigm of fault diagnosis in dynamic systems as an alternative to the well-established observer-based framework.

Graph neural network-based fault diagnosis: a review

no code implementations16 Nov 2021 Zhiwen Chen, Jiamin Xu, Cesare Alippi, Steven X. Ding, Yuri Shardt, Tao Peng, Chunhua Yang

Graph neural network (GNN)-based fault diagnosis (FD) has received increasing attention in recent years, due to the fact that data coming from several application domains can be advantageously represented as graphs.

Application of the unified control and detection framework to detecting stealthy integrity cyber-attacks on feedback control systems

no code implementations27 Feb 2021 Steven X. Ding, Linlin Li, Dong Zhao, Chris Louen, Tianyu Liu

It is demonstrated, in the unified framework of control and detection, that all kernel attacks can be structurally detected when not only the observer-based residual, but also the control signal based residual signals are generated and used for the detection purpose.

Curriculum-based Deep Reinforcement Learning for Quantum Control

no code implementations31 Dec 2020 Hailan Ma, Daoyi Dong, Steven X. Ding, Chunlin Chen

Deep reinforcement learning has been recognized as an efficient technique to design optimal strategies for different complex systems without prior knowledge of the control landscape.

Gradient Monitored Reinforcement Learning

no code implementations25 May 2020 Mohammed Sharafath Abdul Hameed, Gavneet Singh Chadha, Andreas Schwung, Steven X. Ding

The proposed method which we term as Gradient Monitoring(GM), is an approach to steer the learning in the weight parameters of a neural network based on the dynamic development and feedback from the training process itself.
