Zero-dynamics Attack, Variations, and Countermeasures
Hyungbo Shim, Juhoon Back, Yongsoon Eun +2
This chapter presents an overview on actuator attacks that exploit zero dynamics, and countermeasures against them. First, zero-dynamics attack is re-introduced based on a canonica…
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…
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…
Yet Another Tutorial of Disturbance Observer: Robust Stabilization and Recovery of Nominal Performance
Hyungbo Shim, Gyunghoon Park, Youngjun Joo +2
This paper presents a tutorial-style review on the recent results about the disturbance observer (DOB) in view of robust stabilization and recovery of the nominal performance. The…
