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…

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…

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…
