Data-Driven Unknown Input Reconstruction for MIMO Systems with Convergence Guarantees
Enno Breukelman, Takumi Shinohara, Joowon Lee +1
In this paper, we consider data-driven reconstruction of unknown inputs for deterministic, linear time-invariant (LTI) multiple-input multiple-output (MIMO) systems. We propose a n…
Singular Port-Hamiltonian Systems Beyond Passivity
Henrik Sandberg, Kamil Hassan, Heng Wu
In this paper, we investigate a class of port-Hamiltonian systems with singular vector fields. We show that, under suitable conditions, their interconnection with passive systems e…
On the Stealth of Unbounded Attacks Under Non-Negative-Kernel Feedback
Kamil Hassan, Henrik Sandberg
The stealth of false data injection attacks (FDIAs) against feedback sensors in linear time-varying (LTV) control systems is investigated. In that regard, the following notions of…
On Frequency-Weighted Extended Balanced Truncation
Sribalaji C. Anand, Henrik Sandberg
This paper addresses the problem of frequency-weighted extended balanced truncation for discrete and continuous-time linear time-invariant plants. We show that the frequency-weight…
Fault Localisation in Infinite-Dimensional Linear Electrical Networks
Daniel Selvaratnam, Alessio Moreschini, Amritam Das +2
We present a novel fault localisation methodology for linear time-invariant electrical networks with infinite-dimensional edge dynamics and uncertain fault dynamics. The theory acc…
Frequency-Domain Bounds for the Multiconductor Telegrapher's Equation
Daniel Selvaratnam, Alessio Moreschini, Amritam Das +2
We establish mathematical bounds on the chain, ABCD and immittance matrices of a multiconductor transmission line, based on the Telegrapher's equation. Closed-form expressions for…
Feasibility of Randomized Detector Tuning for Attack Impact Mitigation
Sribalaji C. Anand, Kamil Hassan, Henrik Sandberg
This paper considers the problem of detector tuning against false data injection attacks. In particular, we consider an adversary injecting false sensor data to maximize the state…
Electrical Fault Localisation Over a Distributed Parameter Transmission Line
Daniel Selvaratnam, Amritam Das, Henrik Sandberg
Motivated by the need to localise faults along electrical power lines, this paper adopts a frequency-domain approach to parameter estimation for an infinite-dimensional linear dyna…
