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.

这笔赠款将为40名与会者提供参加2020年6月1日至3日在马里兰州学院公园举行的第五届深井钻井系统非线性动力学和控制国际研讨会的机会，他们将在会上出席技术报告并参加关于深井钻井未来的小组会议。本课程将集中于深井钻井系统中的下列新兴主题：通过分析、实验和计算建立钻柱模型、钻柱的非线性动力学以及钻柱的控制。与会者将讨论在粘滑动力学、定向钻井的非线性建模、依赖状态的延迟效应以及基于偏微分系统的控制方案方面出现的挑战。将讨论实地面临的问题和可为解决这些问题而采取的发展，以及与水平钻井和深水钻井相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，以及深井钻井系统行业中使用的方法和方法。这次座谈会将提供建模、非线性动力学和非线性控制可以用来解决实践中面临的挑战的方法，而不仅仅是深井钻井系统的考虑应用。其他领域的例子包括涉及柔性转子和其他分布参数系统的领域，以及制造领域。除了30名技术专家外，还将邀请10名学生、博士后研究人员和初级教职员工，特别是少数民族和代表性不足的群体参加这次研讨会，向他们介绍这一领域，并鼓励他们参与未来的努力。这次座谈会对他们来说将是一次非同寻常的学习经历。此外，这次座谈会可以作为未来学术界和工业界参与的座谈会和研讨会的模板。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
