Inversion of the Multiplicative Matrix Compound Operator
Debojyoti Dey, Ron Ofir, Christian Grussler
The paper investigates how to recover a matrix whose k‑th multiplicative compound equals a given matrix M, showing infinitely many solutions when rank(M) ≤ 1 and a unique solution…
Model-Free Disturbance Observer with Online Modification: Listening to MFDOOM
Nadav Barak, Christian Grussler
Data-Enabled Predictive Control (DeePC) has recently emerged as a framework for controlling unknown systems from data. However, its performance relies on the relevance of the colle…
Efficient -Sign Consistency Verification of Hankel Matrices via Schur Polynomials
Christian Grussler, Tobias Damm
We consider the problem of certifying (strict) -sign consistency of a matrix, that is, whether all of its -th order minors share the same (strict) sign. Although this problem…
Discrete-Time Periodic Monotonicity Preserving Systems
Christian Grussler
Two nested classes of discrete-time linear time-invariant systems, which differ by the set of periodic signals that they leave invariant, are studied. The first class preserves the…
On System Operators with Variation Bounding Properties
Christian Grussler, Chaim Roth, Kang Tong
The property of linear discrete-time time-invariant system operators mapping inputs with at most sign changes to outputs with at most sign changes is investigated. We s…
