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，使模型更加逼真，更易于应用。这就要求在许多基础领域的研究方向上进行一些基本的改变。这些科学家多年来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。该研讨会将涉及这类系统的纯动力学方面的专家，以便可以生成具有更现实预测的改进模型，以及处理系统参数中有界不确定性的李雅普诺夫形式主义专家，以便在面对不确定性时可以采取控制行动。一系列的应用领域也打算扩大，使交叉的信息之间的各种学科，具有相同类型的基础问题可以受到影响。过去的经验表明，这种信息的交叉导致了研讨会与会者之间的新想法和新的合作研究项目。1986年至2000年期间，迄今已举办了11次讲习班。前五届会议在美国南加州大学举行，主要聚集了来自美国和环太平洋地区的科学家和工程师，偶尔也有来自其他国家的科学家参加。为了在从事这一领域工作的美国和西欧科学家和工程师之间开展技术交流，在维也纳（奥地利）和乌尔姆（德国）举行了下两次研讨会。东欧科学界参加了在索普隆（匈牙利）举行的由国家科学基金会和匈牙利科学院共同赞助的讲习班。1997年的讲习班在里约热内卢举行，由巴西科学部赞助。这次研讨会表明，有许多科学家在南美洲的动力系统和控制领域工作。第十期讲习班在Lambrecht（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织委员会再次选择巴西，第11期讲习班于2000年在巴西举行。国际组织委员会已决定在美国洛杉矶举办下一次研讨会，将整整十年后的地点带回研讨会最初的地点。研讨会将在南加州大学举行。这次研讨会的主旨之一是把更多的精力放在让初级教师（特别是女教师）和研究生，这样他们就有更多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，他们的每一份论文集都以特刊或书籍的形式出版，使人们认识到，今天有大量的科学家在南美洲、前苏联以及西欧和东欧国家，如德国、法国、俄罗斯和乌克兰工作，在类似的动力学和控制领域。特别是最近的三次会议已经明确指出，来自欧洲、南美和前苏联的科学家之间需要加强交流。这些国家似乎有大量的信息是美国科学家和工程师所不知道的。在这一重要领域与这些国家的同行交流信息将有益于美国的工程和科学界。过去，这些研讨会不仅在美国与会者之间，而且在美国和不同国家的研究人员之间开展了合作研究项目;其中一些联合研究项目得到了NSF的资助。因此，我们一如既往地期望，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长期合作开辟新的途径。我们希望，这将是更真实的这个特殊的研讨会，因为它的重点将更多的初级教师谁可能更积极和进取。

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.
