Passivity-Based Generalization of Primal-Dual Dynamics for Non-Strictly Convex Cost Functions
Shunya Yamashita, Takeshi Hatanaka, Junya Yamauchi +1
In this paper, we revisit primal-dual dynamics for convex optimization and present a generalization of the dynamics based on the concept of passivity. It is then proved that supply…
Passivity-Based Control of Human-Robotic Networks with Inter-Robot Communication Delays and Experimental Verification
J. Yamauchi, M. W. S. Atman, T. Hatanaka +2
In this paper, we present experimental studies on a cooperative control system for human-robotic networks with inter-robot communication delays. We first design a cooperative contr…
3-D Visual Coverage Based on Gradient Descent Techniques on Matrix Manifold and Its Application to Moving Objects Monitoring
Takeshi Hatanaka, Riku Funada, Masayuki Fujita
This paper investigates coverage control for visual sensor networks based on gradient descent techniques on matrix manifolds. We consider the scenario that networked vision sensors…
Cooperative Environmental Monitoring for PTZ Visual Sensor Networks: A Payoff-based Learning Approach
Takeshi Hatanaka, Yasuaki Wasa, Masayuki Fujita
This paper investigates cooperative environmental monitoring for Pan-Tilt-Zoom (PTZ) visual sensor networks. We first present a novel formulation of the optimal environmental monit…
Vision-Based Cooperative Estimation of Averaged 3D Target Pose under Imperfect Visibility
Takeshi Hatanaka, Takayuki Nishi, Masayuki Fujita
This paper investigates vision-based cooperative estimation of a 3D target object pose for visual sensor networks. In our previous works, we presented an estimation mechanism calle…
Cooperative Estimation of 3D Target Motion via Networked Visual Motion Observer
Takeshi Hatanaka, Masayuki Fujita
This paper investigates cooperative estimation of 3D target object motion for visual sensor networks. In particular, we consider the situation where multiple smart vision cameras s…
Payoff-based Inhomogeneous Partially Irrational Play for Potential Game Theoretic Cooperative Control of Multi-agent Systems
Tatsuhiko Goto, Takeshi Hatanaka, Masayuki Fujita
This paper handles a kind of strategic game called potential games and develops a novel learning algorithm Payoff-based Inhomogeneous Partially Irrational Play (PIPIP). The present…
