International: Experimental Evaluation of Coordinated Flexible Satellite Control

0228865 Singhose这个奖项支持一个为期一年的合作国际论文增强项目。 该项目的首席研究员是亚特兰大格鲁吉亚理工学院的威廉·辛格斯。 日本的合作者是东京工业大学的松永三郎。 他们将对协调灵活的卫星控制进行实验性评价研究。 带柔性附件的航天器的精确控制是极其困难的。 当几个灵活的航天器必须像编队飞行那样精确地和协同地控制时，这项任务的复杂性被放大了许多倍。 卫星协调控制要求一组航天器在保持彼此相对位置和速度的同时，沿期望的轨道飞行。 东京工业大学的二维航天器动力学模拟器是为了验证机器人卫星集群系统而建造的。 该项目的两个目标是：1）评估三颗协调卫星的减振开关推力器剖面，2）评估由系绳连接的三颗协调卫星的减振开关推力器剖面。 该项目汇集了两个具有互补专业知识和研究能力的实验室的努力。 合作将提供巨大的互惠互利，并可以在三个方面推进研究领域：1）所提出的卫星推进器控制方法的实验验证将使卫星控制系统设计的显着进步; 2)扩展到多个协调的航天器将极大地扩展先前为单个独立航天器开发的开关式推进器控制方法的效用，并且3）装备有开关式推进器的卫星将能够更快、更精确地操纵，并且具有更少的残余振动。 该项目通过一名研究生的参与促进国际人力资源。 通过交流思想和技术，该项目将扩大我们的基础知识，促进国际理解与合作。 研究结果将在科学会议和科学期刊上传播。

0228865SinghoseThis award supports a one-year collaborative international dissertation enhancement project. The principal investigator for the project is William Singhose at Georgia Tech in Atlanta. The Japanese collaborator is Saburo Matunaga at the Tokyo Institute of Technology. They will be undertaking research on an experimental evaluation of coordinated flexible satellite control. The precise control of spacecraft with flexible appendages is extremely difficult. The complexity of this task is magnified many times when several flexible spacecraft must be controlled precisely and collaboratively as in formation flying. Coordinated satellite control requires a group of spacecraft to fly in a desired trajectory while maintaining relative position and velocity with respect to each other. The Two-Dimensional Spacecraft Dynamics Simulator at the Tokyo Institute of Technology was constructed to verify the Robot Satellite Cluster Systems. The two objectives of the project are to: 1) evaluate vibration reducing on-off thruster profiles for three coordinated satellites and 2) evaluate vibration reducing on-off thruster profiles for three coordinated satellites that are connected by tethers. The project brings together the efforts of two laboratories that have complementary expertise and research capabilities. The collaboration will offer great mutual benefits and could advance the research field in three ways: 1) experimental verification of the proposed satellite thruster control method will enable a significant advancement in satellite control system design; 2) the extension to multiple, coordinated spacecraft will greatly expand the utility of the on-off thruster control methods developed previously for single, independent spacecraft and 3) satellites equipped with on-off thrusters will be able to maneuver faster, more accurately, and with less residual vibration. The project advances international human resources through the participation of a graduate student. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. Results of the research will be disseminated at scientific meetings and in scientific journals.
