Dual Representations and Proxy Characterization of Norm for Partial Integral Equations

Danilo Braghini, Tristan Thomas, Sachin Shivakumar +2

Duality and dual representations are essential tools for systems theory and controller synthesis. For any finite-dimensional causal linear time-invariant (CLTI) system, there exist…

Comparing Spatially Periodic Feedback and Space-Time Modulation for Unidirectional Wave Propagation in a 1D Mass-Spring-Damper System

João H. S. Brandão, Danilo Braghini, José R. F. Arruda

Unidirectional wave propagation has emerged as a key concept in the dynamics of non-reciprocal mechanical and acoustic metamaterials. This work investigates two fundamentally disti…

Static Output Feedback Stabilization of Linear Systems with Multiple Delays

Danilo Braghini, Eduardo S. Tognetti, Matthew M. Peet

This work proposes a new procedure for the stabilization of time-delay systems using Static Output Feedback (SOF) control. A previous convex optimization approach to SOF for Ordina…
