Passivity-Based Control and Estimation in Networked Robotics and Vision
Assistant Professor, Department of Mechanical and Control Engineering, Tokyo Institute of Technology
Abstract: This talk introduces a series of our research outcomes on passivity-based
estimation and control in networked robotics and vision. The former part discusses how passivity is utilized for visual feedback motion estimation and control. After pointing out inherent passivity in 3-D rigid-body motion, we present a passivity-based 3-D motion estimation mechanism, termed visual motion observer, and the observer-based camera control scheme. It is also shown that the presented framework can successfully incorporate other passive components like an object motion model and a manipulator dynamics while ensuring stability of the total system, owing to passivity preservation property w.r.t. feedback connections. The second part investigates passivity-based cooperative control and estimation. We first introduce a basic idea of synchronizing passive dynamical components under local interactions. Based on the approach, we then address 3-D motion coordination problems
of a network of rigid bodies. The presented results are also extended to flocking in three dimensions,
making use of the energy-based property of the passivity approach. Finally, we address visual feedback motion coordination and cooperative motion estimation, combining the ideas of the above two parts.
A book compiling the contents of this talk will be published in 2015 (expected).
