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 to linear time-invariant (LTI) multiple-input multiple-output (MIMO) systems. We propose a novel autoregress…
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…
Data-Driven Estimation of Vinnicombe metric
Margarita A. Guerrero, Henrik Sandberg, Cristian R. Rojas
Quantifying model mismatch in a control-relevant manner is fundamental in robust control. A well-known metric for this purpose is the -gap, or Vinnicombe metric, which measures…
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…
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…
