Workshop on Dynamics and Control, August 19-21, 2002, Los Angles, California

技术及其副产品的快速发展要求提高相关现象的数学建模精度，使模型更接近实际，更易于应用。这需要在许多基本领域的研究方向上做出一些根本性的改变。多年来，有关科学家一直致力于推动分析动力学和控制以及复杂非线性系统控制中先进方法的应用。研讨会将有这类系统的纯动力学方面的专家参加，以便产生具有更现实预测的改进模型，以及李亚普诺夫形式的专家，用于处理系统参数中的有界不确定性，以便能够在面对不确定性时采取控制行动。还打算提出一系列应用领域，以便在具有相同类型的基本问题的不同学科之间实现信息的交叉。过去的经验表明，这种信息的交叉使讲习班与会者产生了新的想法和新的合作研究项目。到目前为止，在1986年至2000年期间已举办了11个讲习班。前五次是在美国南加州大学举行的，他们帮助聚集了主要来自美国和环太平洋地区的科学家和工程师，偶尔也有其他国家的科学家参加。为了推动在这一领域工作的美国和西欧科学家和工程师之间的技术交流，随后在维也纳(奥地利)和乌尔姆(德国)举办了两期讲习班。东欧科学界参加了以下在索普隆(匈牙利)举办的讲习班，该讲习班由国家科学基金会和匈牙利科学院共同赞助。1997年的讲习班在里约热内卢举行，由巴西科学部赞助。该研讨会表明，在南美洲，有许多科学家从事动力系统和控制领域的工作。第十期讲习班在兰布雷希特(德国)举行，由大众汽车公司和国家科学基金会共同赞助。在南美洲工作的大批科学家和工程师促使国际组委会再次选择巴西，第11次研讨会于2000年在巴西举行。国际组委会已经决定在美国洛杉矶举办下一次研讨会，这将使整整十年后的地点回到研讨会的发源地。工作坊将在南加州大学举行。这一特殊研讨会的主要目的之一是更多地关注吸引初级教员(特别是女教员)和研究生，这样他们就有更大的机会接触到动力学和控制领域更成熟的社区，这样他们就有机会与在美国以外工作的同行互动。这些研讨会的每一期都以专刊或书籍的形式发表，导致人们意识到，今天有大量科学家在南美、前苏联以及德国、法国、俄罗斯和乌克兰等西欧和东欧国家工作。在类似的动力学和控制领域。特别是最近的三次会议明确指出了加强欧洲、南美和前苏联科学家之间的互动的必要性。似乎在这些国家收集了大量美国科学家和工程师尚不知道的信息。与我们在这些国家的同事交流这一重要领域的信息将有利于美国的工程界和科学界。过去，这些研讨会导致了合作研究项目，不仅在美国与会者之间，而且在来自美国和来自不同国家的研究人员之间；其中一些联合研究项目得到了NSF的资助。因此，我们一如既往地期待，即将举行的讲习班将为科学家和工程师之间通过联合研究项目开展合作研究和持续的长期合作开辟新的途径。我们希望，这一点将更适用于这次特别的研讨会，因为它的重点将更多地放在可能更活跃和更有进取心的初级教职员工身上。

The rapid development of technology and its by-products require increasedprecision in mathematical modeling of the relevant phenomena to make themodels more realistic and more readily applicable. This has required somebasic changes in the direction of research in many fundamental areas. Thescientists concerned have been involved for some years now in promoting theuse of advanced methods in Analytical Dynamics and Control, and in theControl of Complex Nonlinear Systems. The workshop will involve experts bothin the purely dynamical aspects of such systems so that improved models withmore realistic predictions can be generated and experts in Lyapunovformalisms for handling bounded uncertainties in system parameters so thatcontrol actions can be made in the face of uncertainties. A range ofapplication areas is also intended to be broached, so that a crossover ofinformation between various disciplines that have the same types offundamental problems can be effected. Past experience has shown that suchcrossover of information has led to new ideas and new collaborative researchprojects among attendees of the workshop. Eleven workshops have been held to date between 1986 and 2000. The firstfive were held in the US at the University of Southern California, and theyhelped to get together scientists and engineers mainly from the US and thePacific Rim, with occasional participation from scientists from othercountries. In an effort to initiate a technical exchange between US and WestEuropean scientists and engineers who are working in this area, the next twoworkshops were held in Vienna (Austria) and Ulm (Germany). The East Europeanscientific community was drawn into the following workshop in Sopron(Hungary), which was co-sponsored by NSF and the Hungarian Academy ofSciences. The 1997 workshop was held in Rio de Janeiro and was sponsored bythe Brazilian Ministry of Science. This workshop indicated that there werenumerous scientists working in the area of Dynamical systems and Control inSouth America. The tenth workshop was held in Lambrecht (Germany) and wasco-sponsored by the Volkswagen Corporation and the National ScienceFoundation. The large community of scientists and engineers working in SouthAmerica caused the International Organizing Committee to select Brazil yetanother time, and the 11th workshop was held in Brazil in 2000. It has been decided by the International Organizing Committee to have thenext workshop in the US, in Los Angeles, bringing the venue after an entiredecade back to the location from which the workshops initiated. The workshopwill be held at the University of Southern California. One of the mainthrusts of this particular workshop is to focus more on bringing juniorfaculty (especially women-faculty) and graduate students, so that they canhave a greater chance of increased exposure to the more establishedcommunity in the area of dynamics and control, and so that they can have anopportunity to interact with their counterparts who are working outside theUS.These workshops, each of whose proceedings have been published either asspecial journal issues or as books, have led to the realization that thereare today a large number of scientists who are working in South America, theformer USSR, as well as both West and East European countries like Germany,France, Russia and the Ukraine, in similar areas of dynamics and control. Inparticular the last three meetings have clearly pointed out the need forincreased interaction between scientists from Europe, South America, and theformer USSR. There appears to be a substantial body of information gatheredin these countries that is yet unknown to US scientists and engineers. Anexchange of information in this important area with our colleagues in thesecountries will be beneficial to the engineering and scientific communityhere in the US. These workshops have led, in the past, to collaborativeresearch projects, not only among the US attendees but also betweeninvestigators from the US and those from different countries; some of thesejoint research projects have been funded by NSF. We therefore expect, asbefore, that the forthcoming workshop will open up new avenues forcollaborative research and sustained long-term cooperation among scientistsand engineers through joint research projects. This, we hope, will be moreso true for this particular workshop, since its focus will be more on juniorfaculty who may be more active and enterprising.
