Fifth International Colloquium on Nonlinear Dynamics and Control of Deep Drilling Systems; College Park, Maryland; 1-3 June 2020

该资助将提供40名与会者，其中一些来自代表性不足的群体，有机会参加2020年6月1日至3日在马里兰州大学公园举行的第五届深钻井系统非线性动力学与控制国际研讨会，他们将参加技术演讲并参加关于深钻井未来的小组会议。讲座集将集中于以下深钻系统的新兴主题：通过分析、实验和计算的钻柱建模，钻柱的非线性动力学，以及钻柱的控制。与会者将解决在粘滑动力学、定向钻井非线性建模、状态相关延迟效应和基于偏微分系统的控制方案等背景下出现的挑战。将讨论该领域面临的问题和为解决这些问题可以采取的发展措施，以及与水平钻井和深水钻井有关的当前和未来方向。研讨会将为研究生、博士后研究人员和初级教师提供一个机会，让他们了解涉及非线性动力学和非线性控制的复杂问题，以及深钻系统行业中使用的方法和方法。本次研讨会可以提供建模、非线性动力学和非线性控制的方法，以解决实践中面临的挑战，而不仅仅是深钻系统的应用。其他领域的例子包括那些涉及柔性转子和其他分布式参数系统以及制造业的领域。除了30名技术专家外，10名学生、博士后研究人员和初级教师，特别是少数民族和代表性不足的群体，将被邀请参加本次研讨会，向他们介绍该领域，并鼓励他们参与未来的努力。这次研讨会对他们来说是一次特殊的学习经历。此外，这次专题讨论会可作为今后学术界和工业界参加的专题讨论会和讲习班的模板。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This grant will provide 40 attendees, several of whom are from under-represented groups, the opportunity to participate in the Fifth International Colloquium on Nonlinear Dynamics and Control of Deep Drilling Systems, in College Park, Maryland, 1-3 June 2020, where they will attend technical presentations and participate in a panel session on the future of deep drilling. The lecture sets will focus on the following emerging topics in deep drilling systems: modeling of drill strings through analysis, experiments, and computations, nonlinear dynamics of drill strings, and the control of drill strings. The participants will address challenges arising in the context of stick-slip dynamics, nonlinear modeling of directional drilling, state-dependent delay effects, and control schemes based on partial differential systems. Discussions will be undertaken on the problems faced in the field and developments that can be pursued to address them, as well as current and future directions associated with horizontal drilling and deep water drilling. The colloquium will serve as an opportunity to expose graduate students, post-doctoral researchers, and junior faculty to complex problems involving nonlinear dynamics and nonlinear control, as well as approaches and methodologies used in the deep drilling systems industry.This colloquium could provide ways in which modeling, nonlinear dynamics, and nonlinear control can be used to tackle challenges faced in practice, beyond the considered application of deep drilling systems. Examples of other areas include those that involve flexible rotors and other distributed parameter systems, and manufacturing. In addition to 30 technical experts, 10 students, post-doctoral researchers, and junior faculty members, in particular, minorities and underrepresented groups, will be invited to participate in this colloquium to introduce them to the field as well as encourage their participation in future efforts. This colloquium is expected to be an exceptional learning experience for them. Furthermore, this colloquium can serve as a template for future colloquia and workshops involving academia and industry.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
