Development of Adaptive Hybrid Control Techniques for Building Structures

本项目的目标是开发一种新型的建筑结构混合控制系统。该系统旨在利用主动控制的效率和灵活性，同时保持被动系统的安全性和可靠性。为了实现这一目标，将开发一种螺杆千斤顶或减震器类型的执行器，包括被动和主动减振机制。这样的装置将安装在具有配置传感器的结构支撑中，并且可以很容易地分布在结构中的多个位置。为了实现这样一个系统，将探索基于鲁棒和自适应控制概念的不同控制算法。优化技术将用于确定主动/被动控制设备和传感器的最佳配置，最大限度地提高控制系统的效率和安全性。该混合动力系统最终将通过实验室测试进行验证。这项研究将通过跨学科的努力进行，涉及来自结构、电气、和航空航天工程。这项研究将有助于开发更安全、更有效的建筑结构在风和地震激励下的控制系统。

The objective of this project is to develop a novel hybrid control system for building structures. The system is intended to exploit the efficiency and flexibility of active control, while maintaining the safety and reliability of passive systems. To achieve this objective, a screw-jack or shock- absorber type of actuator that incorporates both passive and active damping mechanisms will be developed. Such devices are to be installed in structural braces with collocated sensors, and can be easily distributed at multiple locations in a structure. To implement such a system, different control algorithms based on robust and adaptive control concepts will be explored. Optimization techniques will be used to determine the optimal allocation of active/passive control devices and sensors, and to maximize both the efficiency and safety of the control system. The hybrid system will be finally validated by laboratory tests. The study will be carried out with an interdisciplinary effort involving researchers from structural, electrical, and aerospace engineering. The research will lead to the development of safer and more effective control systems for building structures under wind and earthquake excitations.
