Distributed Design of Glocal Controllers via Hierarchical Model Decomposition
Hampei Sasahara, Takayuki Ishizaki, Jun-ichi Imura +2
This paper proposes a distributed design method of controllers having a glocal (global/local) information structure for large-scale network systems. Distributed design, independent…
Power Injection Attacks in Smart Distribution Grids with Photovoltaics
Martin Lindström, Hampei Sasahara, Xingkang He +2
In order to protect smart distribution grids from intrusions, it is important to understand possible risks and impacts of attacks. We study the worst-case attack strategy of a powe…
Disconnection-aware Attack Detection and Isolation with Separation-based Detector Reconfiguration
Hampei Sasahara, Takayuki Ishizaki, Jun-ichi Imura +1
This study addresses incident handling during an adverse event for dynamical networked control systems. Incident handling can be divided into five steps: detection, analysis, conta…
Parameterization of All Output-Rectifying Retrofit Controllers
Hampei Sasahara, Takayuki Ishizaki, Jun-ichi Imura
This study investigates a parameterization of all output-rectifying retrofit controllers for distributed design of a structured controller. It has been discovered that all retrofit…
Asymptotic Security of Control Systems by Covert Reaction: Repeated Signaling Game with Undisclosed Belief
Hampei Sasahara, Serkan Saritas, Henrik Sandberg
This study investigates the relationship between resilience of control systems to attacks and the information available to malicious attackers. Specifically, it is shown that contr…
