学术讲座：Foundations of Battery Supported Cyber-Physical Systems with Applications in Bio-inspired Marine Autonomy 时间：2015年10月26日，星期一，上午10：30-11：30 地点：望江校区基础教学楼A318 讲座人：美国乔治亚理工学院（Georgia Institute of Technology）副教授 Dr.Fumin Zhang ABSTRACT: The Ocean is playing an ever more important role for the future of mankind. Larger variety of marine robots have been developed and commercialized during the last two decades, which posts higher goals for autonomy that have never been achieved before in marine environments. This talk introduces recent work in the development of foundations for battery supported Cyber-Physical systems with focus on its impact in marine autonomy. We discuss a novel analytical approach to quantify robustness for scheduling and battery management, which are important to marine robots. A dynamic schedulability test is introduced to determine whether tasks are schedulable within a finite time window. The test is used to measure robustness of a real-time scheduling algorithm by evaluating the strength of the perturbations that break schedulability at runtime. Robustness of battery management is quantified analytically by a threshold on the state of charge. An adaptive threshold is derived that not only guarantees robustness, but also significantly reduces the false alarm rate to prolong operational life of batteries. We will discuss our recent contributions on a multidisciplinary investigation of autonomous collective foraging in a complex environment that explicitly integrates insights from biology with models and provable strategies from control theory. The methods are rigorously developed and tightly integrated with experimental effort.
