研究実績の概要

The goal of this research is to enhance "supervisor localization" with several features for practical distributed control of discrete-event systems. In the first year, the following new results have been achieved.
1. Partial-observation distributed control: Supervisor localization has been extended to the setting where some events are unobservable due to lack of sensors in practice.
2. Delay-robustness of distributed control: Delay robustness of distributed control synthesized by supervisor localisation has been evaluated. This result is useful in demonstrating which events are tolerant of inter-agent communication delay.
3. A prototype warehouse logistic system has been built. This experiment system will serve as testbed for distributed control algorithms we develop throughout this project.

現在までの達成度 (区分)

2: おおむね順調に進展している

理由

In the past year (2016.04-2017.03), we have achieved 3 journal paper publications and 2 conference paper publications. In addition to theoretical development, we have also initiated building an experiment testbed.

今後の研究の推進方策

We plan to develop scalable distributed control, whose control strategies do not depend on the number of agents, and also adaptive control, whose controllers are able to adapt to changes of the environment. In addition, we will further develop our experiment testbed by using real mobile robots for automating (miniature) warehouse logistics.
