Error- and Tamper-Tolerant State Estimation for Discrete Event Systems under Cost Constraints
Yuting Li, Christoforos N. Hadjicostis, Naiqi Wu +1
This paper deals with the state estimation problem in discrete-event systems modeled with nondeterministic finite automata, partially observed via a sensor measuring unit whose mea…
Extended Insertion Functions for Opacity Enforcement
Xiaoyan Li, Christoforos N. Hadjicostis, Zhiwu Li
Opacity is a confidentiality property that holds when certain secret strings of a given system cannot be revealed to an outside observer under any system activity. Opacity violatio…
Event-Triggered Quantized Average Consensus via Mass Summation
Apostolos I. Rikos, Christoforos N. Hadjicostis
We study the distributed average consensus problem in multi-agent systems with directed communication links that are subject to quantized information flow. The goal of distributed…
Stability Analysis of Droop-Controlled Inverter-Based Power Grids via Timescale Separation
Stefanos Baros, Christoforos N. Hadjicostis, Francis O'Sullivan
We consider the problem of stability analysis for distribution grids with droop-controlled inverters and dynamic distribution power lines. The inverters are modeled as voltage sour…
