Experimental and analytical investigations of hybrid control systems designed to combine passive damping provided by cladding- structure interaction with robust active control systems will be conducted in this project. Experienced gained in the study of advanced cladding connection systems designed to be employed in buildings as passive energy dissipation and stiffness augmentation systems will be put to advantage in this investigation. The research plan is organized into five primary tasks: (1) Use of cladding as a passive control system; (2) Application of classical, modern, robust and pulse control to buildings; (3) Development of possible hybrid control systems; (4) Performance evaluation; and (5) Model experiments (and plans for future testing). The research will be carried out by an interdisciplinary team of researchers that combines active and practical involvement in earthquake engineering with broad experience in the development and application of robust control theory. Interaction among the proposed multidisciplinary team members will be in the areas of dynamic modelling (including modelling of uncertainties), trade- off studies related to the relative degrees of passive versus active damping, and experimental validation. Results of the overall research effort are expected to contribute: (1) innovative approaches to robust control of building structures (both active and passive), and (2) innovative methods for combining engineered passive damping systems with modern robust controllers to achieve practice building control systems that can be applied to earthquake and other dynamic loading conditions.

该项目将进行混合控制系统的实验和分析研究，该系统旨在将包层结构相互作用提供的被动阻尼与稳健的主动控制系统相结合。 在研究设计用于建筑物中作为被动能量耗散和刚度增强系统的先进包层连接系统方面获得的经验将在本次研究中得到利用。 该研究计划分为五个主要任务：（1）使用包层作为被动控制系统； （2）古典、现代、鲁棒、脉冲控制在建筑中的应用； (3) 开发可能的混合控制系统； （四）绩效评价； （5）模型实验（以及未来测试的计划）。 该研究将由一个跨学科的研究团队进行，该团队结合了对地震工程的积极和实际参与以及鲁棒控制理论开发和应用的丰富经验。 拟议的多学科团队成员之间的互动将涉及动态建模（包括不确定性建模）、与被动与主动阻尼相对程度相关的权衡研究以及实验验证。 总体研究工作的成果预计将有助于：(1) 建筑结构鲁棒控制的创新方法（主动和被动），以及 (2) 将工程被动阻尼系统与现代鲁棒控制器相结合的创新方法，以实现可应用于地震和其他动态载荷条件的实践建筑控制系统。
