State Estimation and Tracking Control for Hybrid Systems by Gluing the Domains
Jisu Kim, Hyungbo Shim, Jin Heon Seo
We study the design problems of state observers and tracking controllers for a class of hybrid systems whose state jumps. The idea is to utilize the well-known method of gluing the…
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…
A Tool for Analysis and Synthesis of Heterogeneous Multi-agent Systems under Rank-deficient Coupling
Jin Gyu Lee, Hyungbo Shim
The behavior of heterogeneous multi-agent systems is studied when the coupling matrices are possibly all different and/or singular, that is, its rank is less than the system dimens…
A Zero-stealthy Attack for Sampled-data Control Systems via Input Redundancy
Jihan Kim, Gyunghoon Park, Hyungbo Shim +1
In this paper, we introduce a new vulnerability of cyber-physical systems to malicious attack. It arises when the physical plant, that is modeled as a continuous-time LTI system, i…
Initialization-free Privacy-guaranteed Distributed Algorithm for Economic Dispatch Problem
Hyeonjun Yun, Hyungbo Shim, Hyo-Sung Ahn
This paper considers the economic dispatch problem for a network of power generators and customers. In particular, our aim is to minimize the total generation cost under the power…
