CAREER: Robust Control-Oriented Identification: Theoretical Development and Experimental Validation

采用的总体技术方法是理论、仿真和实验相结合，并从数学、控制理论、数值计算、结构动力学和控制系统实现等领域汲取理论概念和技术。在我们的理论方法中，一个独特的线索是使用经典的解析函数插值和凸优化技术，这些技术似乎非常有用，但尚未被用于系统识别。提出的研究以模型和计算复杂性为统一主题，重点关注几个最紧迫的问题，这些问题尚未得到解决，但对鲁棒控制导向识别技术的进步和应用至关重要，旨在开发以前没有的准确，计算效率高且实际可行的识别算法。涉及柔性结构、涡轮机械和主动磁轴承的数值模拟和实验验证将在实验室进行，并与政府和工业组织合作。教育和人力资源开发是这项拟议研究的一个组成部分。本研究的主要教育目标是为学生提供参与高级研究项目的机会。通过这个严谨、创新和严格指导的研究项目，学生将获得和发展科学探究和技术发现的知识、技能和方法，从而为他们未来的工程职业生涯做好充分的准备。通过结合学生咨询、课程开发、实验室开发和公共服务等活动，采用精心协调、平衡和系统的教育方法来实现这一目标。虽然博士和硕士研究生将直接参与这项研究，但该项目也将通过暑期研究和从这项研究中产生的高年级设计项目使高年级本科生受益。＊＊＊

9623228 Chen The overall technical approach to be adopted is to merge theory, simulation, and experimentation, and it draws theoretical concepts and techniques from the areas of mathematics, control theory, numerical computation, structural dynamics, and control system implementation. A unique thread in our theoretical approach is the use of classical analytic function interpolation and convex optimization techniques which appear to be extremely useful but are yet to be exploited for system identification. The proposed research, with a unifying theme on model and computational complexity, focuses on several most imminent issues that are yet to be addressed but are critical to the advance and application of robust control-oriented identification techniques, and it aims at developing accurate, computationally efficient and practically feasible identification algorithms not previously available. Numerical simulation and experimental validation involving flexible structures, turbo-machines, and active magnetic bearings will be performed in laboratory, and in collaboration with government and industrial organizations. Education and human resource development constitutes an integrable part in this proposed research. The principal education objective in this research is to provide students opportunities to participate in advanced research projects. Through this rigorous, innovative, and closely guided research program, the students will acquire and develop knowledge, skills, and methods of scientific inquiry and technological discovery, hence adequately preparing them for an engineering career in the future. A carefully coordinated, balanced,and systematic educational approach through a combination of activities in student advising, curriculum development, laboratory development, and public services will be employed to achieve this goal. While graduate students at the Doctoral and the Masters levels will participate directly in this research, the project will also benefit Senior undergraduate students through summer research and Senior design projects generated from this research. ***
