Guidance Of 3d Underwater Non-Holonomic Vehicle Via Projection On Holonomic Solutions
- in Symposium on Underwater Robotic Technology SURT 2000, World Automation Congress WAC 2000, Maui
, 2000
"... The feedback control of a nonholonomic 3D floating vehicle is considered: namely the control objective is to drive a vehicle moving in 3D space to a given point and heading along a given line having as control inputs a 1D linear velocity (surge velocity) and a 2D angular one allowing the vehicle to ..."

Passive decomposition and control of nonholonomic mechanical systems
- IEEE Trans. on Robo.. Accepted
"... Abstract—We propose nonholonomic passive decomposition, which enables us to decompose the Lagrange–D’Alembert dynamics of multiple (or a single) nonholonomic mechanical systems with a formation-specifying (holonomic) map h into 1) shape system, describing the dynamics of h(q) (i.e., formation aspect ..."

the locked and shape systems individually, we can drive the formation and maneuver aspects simultaneously and separately. Notions of formation/maneuver decoupled controllability are introduced to address limitations imposed by the nonholonomic constraint, along with passivity-based formation/maneuver control
Externally Excited Coordination of Autonomous Formations
"... Abstract — Inspired by the recent “Robot Sheepdog Project ” in the literature, in this paper a new method for coordination of multi-agent systems moving in a 2dimensional region with the obstacles along a collision free trajectory is presented. A two level decentralized control scheme is proposed. A ..."

Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Institutions of society are built to enforce power relationships existing in each historical period, including the controls, limits, and social contracts, achieved in the power struggles. More
Team-triggered coordination of networked systems,”
- in American Control Conference,
, 2013
"... Abstract-This paper proposes an approach for improved methods of performing event-and self-triggered communication and control on networked systems. Current self-triggered strategies are known to be quite conservative whereas event-triggered approaches are costly to implement on distributed systems ..."

systems that rely on wireless communication for information transmission. To overcome these limitations, we propose a novel class of teamtriggered coordination laws that combine ideas from event-and self-triggered control, are implementable on networked systems, and maintain desired levels of performance
Contraction Control of a Fleet Circular Formation of AUVs under Limited Communication Range
- In Proc. of the 2010 American Control Conference
, 2010
"... Abstract-This work proposes a novel control algorithm dedicated to multi-agent systems with nonlinear dynamics. The aim of this paper is for the agents to form a circular formation whose center is fixed and whose radius is given by a time-varying reference. The problem of uniform distribution of al ..."

This communication constraint is tackled by using a cooperative control scheme which includes the Laplacian matrix of the communication graph (distance-dependent). The multi-agent system is simulated
6-DOF Nonlinear Simulation of Vision-based Formation Flight,” AIAA guidance, navigation, and control conference

In this paper, reinforcement learning is applied to coordinate, in a decentralized fashion, the motions of a pair of hydraulic actuators whose task is to firmly hold and move an object along a specified trajectory under conventional position control. The learning goal is to reduce the interaction fo ..."
