U.S.-Germany Cooperative Research on the Interaction of Dynamics and Control Parameters in Mechanical Systems

该奖项支持芝加哥伊利诺伊大学的Ahmed Shabana教授和一名研究生与德国航空航天研究所（DLR）机器人和系统动力学研究所的Richard Schwertassek博士和其他人在工程研究方面进行合作。这个德国组织被广泛认为是欧洲首屈一指的航空航天研究机构之一，如果不是世界上的，参与的研究所因其最先进的研究而受到高度评价。该项目的美国和德国合作伙伴对力学，机电一体化和约束变形体控制的计算方面感兴趣，例如用于绕地球轨道的大型结构。他们的研究目标是为大规模柔性系统的动态分析和控制开发更有效和稳健的方法。更具体地说，他们计划开发新的计算机和数值算法，通过考虑机电一体化和控制参数的影响，有效地解决受约束的可变形体动力学方程。他们打算评估不同线性化方案对控制系统性能的影响，并制定可用于确定特定应用中最有用的动力学和控制方法的准则。此次合作得益于美国团队在计算力学方面和德国团队在柔性系统的实验控制和机电一体化方面的互补专业知识。

This award supports Professor Ahmed Shabana and a graduate student of the University of Illinois at Chicago to collaborate in engineering research with Dr. Richard Schwertassek and others of the Institute of Robotics and System Dynamics of the German Aerospace Research Establishment (DLR.) This German organization is widely recognized as one of the premier aerospace research institutions in Europe if not the world, and the participating institute is very highly regarded for its state-of-the-art research. The US and German partners in this project are interested in computational aspects of the mechanics, mechatronics and control of constrained deformable bodies such as large scale structures intended for orbit around the earth. The goal of their research is to develop more efficient and robust methods for the dynamic analysis and control of large scale flexible systems. More specifically, they plan to develop new computer and numerical algorithms for the efficient solution of constrained deformable body dynamic equations, by taking into account the effects of mechatronics and control parameters. They intend to evaluate the effects of different linearization schemes on control system performance and develop guidelines which can be applied to identify the most useful dynamics and control methodology for a particular application. This collaboration benefits from the complementary expertise of the US group in computational mechanics and the German group in the experimental control and mechatronics of flexible systems.
