Distributed, hierarchical & hybrid control systems

该研究计划的总体目标是推进分布式、递阶和混合(DHH)控制系统的基础研究和工程设计。分布式和分级系统结构被普遍采用来应对系统复杂性，例如，考虑钢铁制造厂的分散和分级控制系统，以及互联网和空中交通控制和网络无线系统的控制系统。此外，混合系统，也就是具有连续和离散状态和动态的系统，是当代工程系统中所采用的技术所固有的，例如，考虑到化学工程和制造过程工业。航天器轨迹控制和空间任务管理系统生动地展示了分布式、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.
