The Geometry of Transmission Zeros in Distance-Based Formations
Solomon Goldgraber Casspi, Daniel Zelazo
This letter presents a geometric input-output analysis of distance-based formation control, focusing on the phenomenon of steady-state signal blocking between actuator and sensor p…
Characterizing bearing equivalence in directed graphs
Zhiyong Sun, Shiyu Zhao, Daniel Zelazo
In this paper, we study bearing equivalence in directed graphs. We first give a strengthened definition of bearing equivalence based on the \textit{kernel equivalence} relationship…
Bearing-based Autonomous Communication Relay Positioning under Field-of-View Constraints
Marco Fabris, Daniel Zelazo
This paper investigates the problem of communication relay establishment for multiple agent-based mobile units using a relay vehicle. The objective is to drive autonomously the rel…
Gradient Free Cooperative Seeking of a Moving Source
Elad Michael, Chris Manzie, Tony A. Wood +2
In this paper, we consider the optimisation of a time varying scalar field by a network of agents with no gradient information. We propose a composite control law, blending extremu…
Product Form of Projection-Based Model Reduction and its Application to Multi-Agent Systems
Noam Leiter, Daniel Zelazo
Orthogonal projection-based reduced order models (PROM) are the output of widely-used model reduction methods. In this work, a novel product form is derived for the reduction error…
Edge-Matching Graph Contractions and their Interlacing Properties
Noam Leiter, Daniel Zelazo
For a given graph of order with edges, and a real symmetric matrix associated to the graph, , the interlac…
Cooperative Manipulation via Internal Force Regulation: A Rigidity Theory Perspective
Christos K. Verginis, Daniel Zelazo, Dimos V. Dimarogonas
This paper considers the integration of rigid cooperative manipulation with rigidity theory. Motivated by rigid models of cooperative manipulation systems, i.e., where the grasping…
Analysis and Synthesis of MIMO Multi-Agent Systems Using Network Optimization
Miel Sharf, Daniel Zelazo
This work studies analysis and synthesis problems for diffusively coupled multi-agent systems. We focus on networks comprised of multi-input multi-output nonlinear systems that pos…
On Certain Properties of Convex Functions
Miel Sharf, Daniel Zelazo
This note deals with certain properties of convex functions. We provide results on the convexity of the set of minima of these functions, the behaviour of their subgradient set und…
