Robust Stability of Discrete-time Disturbance Observers: Understanding Interplay of Sampling, Model Uncertainty and Discrete-time Designs
Gyunghoon Park, Chanhwa Lee, Youngjun Joo +1
In this paper, we address the problem of robust stability for uncertain sampled-data systems controlled by a discrete-time disturbance observer (DT-DOB). Unlike most of previous wo…

Detection of Sensor Attack and Resilient State Estimation for Uniformly Observable Nonlinear Systems having Redundant Sensors
Junsoo Kim, Chanhwa Lee, Hyungbo Shim +2
This paper presents a detection algorithm for sensor attacks and a resilient state estimation scheme for a class of uniformly observable nonlinear systems. An adversary is supposed…

On Redundant Observability: From Security Index to Attack Detection and Resilient State Estimation
Chanhwa Lee, Hyungbo Shim, Yongsoon Eun
The security of control systems under sensor attacks is investigated. Redundant observability is introduced, explaining existing security notions including the security index, atta…
