Distributed, hierarchical & hybrid control systems

该研究计划的总体目标是推进分布式、分层和混合（DHH）控制系统的基础研究和工程设计。分布式和分层系统结构被普遍采用来应对系统复杂性，例如钢铁制造厂的分散和分层控制系统，以及互联网和空中交通管制和网络无线系统的分散和分层控制系统。此外，混合系统，即具有连续和离散状态和动态的系统，是当代工程系统中采用的技术所固有的，例如考虑化学工程和制造过程工业。航天器轨道控制和航天使命管理系统生动地表现出分布式、递阶和混合控制系统的特点。

The overall objective of the proposed research program is to advance the fundamental study and engineering design of distributed, hierarchical and hybrid (DHH) control systems. Distributed and hierarchical system structures are universally employed to contend with system complexity, consider for instance the decentralized and hierarchical control systems of steel manufacturing plants, and those of the Internet and the air-traffic control and network wireless systems. Furthermore, hybrid systems, that is to say systems with both continuous and discrete states and dynamics, are inherent in the technologies employed in contemporary engineering systems, consider, for example, the chemical engineering and manufacturing process industries. Space vehicle trajectory control and space mission management systems vividly display distributed, hierarchical and hybrid control systems features.
