A distributed space system is a collection of physically separated, multiple space vehicles whosestates are coordinated to achieve a local or global objective.The distributed spacecraft paradigm shifts the complexity of the space system design, traditionally associated with the control of large flexible structures,to problems in planning, coordination, inter-spacecraft communication and sensing, and control.The objectives of this project are to (1) develop a hybrid control design methodology which capturesthe interaction between inter-spacecraft communication and sensingon the one hand and the admissible distributed spacecraftcontrol strategies on the other, and (2) develop autonomous maneuver planning and control for distributed space systems.This research leads to novel analysisand synthesis techniques for a class of hybrid dynamic systems that is tailored to capturethe interdependence of communication, sensing, and controlof a distributed system.It also examines a paradigm and a new set of techniques in the matrix inequality approach to pathplanning and control. The education plan is implemented through course and curriculum development, undergraduate and graduate mentoring, and an outreach effort.The undergraduate course focuses on control theory and its applications in the design of space systems,and emphasizes its interdependence on communication and computing technologies. Two graduate courses, Hybrid Systems and Optimization in Systems Sciences,emphasize the recent advances in the modeling,analysis, and design techniques for a specific class of dynamic systems, and lays out a rigorous framework,based on optimization theory and computational techniques, for general dynamic system analysis and synthesis.The outreach effort focuses on an interactive Internet website andtwo teachers' workshops, through which concepts of control and space system engineering are communicated to the high school students and grades 9--12 teachers.

分布式空间系统是物理上分离的多个空间飞行器的集合，它们的状态协调以实现局部或全局目标。分布式航天器范式将空间系统设计的复杂性从传统上与大型柔性结构的控制相关联转移到规划、协调、航天器间通信和传感等问题，本项目的目标是：（1）发展一种混合控制设计方法，一方面考虑航天器间通信和传感之间的相互作用，另一方面考虑可接受的分布式航天器控制策略，（2）发展分布式空间系统的自主机动规划与控制。该研究为一类混合动态系统提供了新的分析与综合技术，和控制的分布式系统。它还探讨了一个范例和一套新的技术，在矩阵不等式的方法，路径规划和控制。该教育计划通过课程和教学大纲编制、本科生和研究生辅导以及外联工作来实施，本科生课程侧重于控制理论及其在空间系统设计中的应用，并强调其与通信和计算技术的相互依赖性。两门研究生课程，系统科学中的混合系统和优化，强调了动态系统特定类别的建模，分析和设计技术的最新进展，并基于优化理论和计算技术，为一般动态系统的分析和综合制定了严格的框架。推广工作集中在一个交互式互联网网站和两个教师研讨会上，通过这些课程，控制和空间系统工程的概念被传达给高中学生和9- 12年级的教师。
