项目摘要

This project is focused on the development of smart hybrid tuned mass damper control for vibration reduction of tall buildings and high-rise structure under multi-hazard environment. An integrated eddy current TMD is proposed, based on which a two-stage hybrid mass damper is developed after incorporating a small AMD. The effect of floor rotation of high-rise structure on performance of TMD is investigated and the classical TMD optimal parameters are modified. .A recursive system identification and model updating method is put forward. Sensor fault detection and fault-tolerant design method will be founded. The ultimate objective is to realize a highly reliable hybrid control system with the capability of long-term implementation. In this research, the control strategy will consider the interaction between the hybrid mass dampers and structure. The model used in the control algorithm will be obtained through a new system identification method, which also considers the sensor time delay in the model. The sensors for feedback control will be diagnosed by a sensor fault detection method in order to fix and maintain the sensor functionality. An intelligent control algorithm is developed to achieve a high-level performance under various loadings. A hybrid control strategy for triggering the active mass driver and switching control laws are developed. To achieve a high-performance and autonomous control system, all components will be merged together. Fulfillment of this research will be able to provide a way to improve the hybrid control technology for tall buildings and high-rise structures. This research is indeed scientifically valuable, realizable, and applicable for engineering practice.
