Reachability Analysis of Nonlinear Discrete-Time Systems Using Polyhedral Relaxations and Constrained Zonotopes
Brenner S. Rego, Guilherme V. Raffo, Marco H. Terra +1
This paper presents a novel algorithm for reachability analysis of nonlinear discrete-time systems. The proposed method combines constrained zonotopes (CZs) with polyhedral relaxat…
ZETA: a library for Zonotope-based EsTimation and fAult diagnosis of discrete-time systems
Brenner S. Rego, Joseph K. Scott, Davide M. Raimondo +2
This paper introduces ZETA, a new MATLAB library for Zonotope-based EsTimation and fAult diagnosis of discrete-time systems. It features user-friendly implementations of set repres…
When Do Large Language Models Exhibit Unsolicited Deception?
Samuel M. Taylor, Benjamin K. Bergen
Large Language Models (LLMs) are effective at deceiving when prompted to do so. Models that demonstrate better performance on reasoning tasks are also better at prompted deception.…
Joint State-Parameter Observer-Based Robust Control of a UAV for Heavy Load Transportation
Brenner S. Rego, Daniel N. Cardoso, Marco. H. Terra +1
This paper proposes a joint state-parameter observer-based controller for trajectory tracking of an octocopter unmanned aerial vehicle (OUAV), for transportation of a heavy load wi…
Line zonotopes: A tool for state estimation and fault diagnosis of unbounded and descriptor systems
Brenner S. Rego, Davide M. Raimondo, Guilherme V. Raffo
This paper proposes new methods for set-based state estimation and active fault diagnosis (AFD) of linear descriptor systems (LDS). Unlike intervals, ellipsoids, and zonotopes, con…
