中文摘要： 地震模拟振动台台阵是国际上振动台研究和发展的方向，由于可实现多维多点地震场激励,振动台台阵试验理论较之传统单振动台试验更为复杂，配套试验方法和控制技术亟需深入研究。而其理论和技术上涉及土木、液压、电子等诸多学科，兼具频带宽、加速度控制等特点，其研究内容丰富，应用前景广阔。本项目组负责了自主研发的北京工业大学九子台振动台台阵系统的建设、开发和运行，完成了多通道联合控制程序的开发和改造，开展了多振动台混合试验研究，完成多维多点振动台台阵试验20余项。为提高振动台台阵系统的波形再现能力和系统性能，本项目提出考虑时频域补偿的多参量反馈闭环控制理论，拟建立考虑试件非线性相互作用、油源压力波动影响的非线性控制系统模型，实现力、加速度联合反馈和集散式自适应同步控制，并对振动台设计理论、加速度同步控制机理、控制参数自整定算法、多参量自适应反馈控制机理、振动台混合控制等开展系统的研究。

英文摘要： It is an international trend on the research and development of shaking table array system. As the multi-dimensional multi-point earthquake excitation, it is more complex than the traditional shaking table system and needs more in-depth study on test methods and control technology. The domestic construction of shaking table array is largely dependent on the technically importation at present. And the investment on the shaking table array research is relatively poor. Shaking table array was involving civil engineering, hydraulic, electronics and many other disciplines in the theoretical and technical, with the characteristics of a wide frequency band and acceleration feedback control, it has a lot of research content and good prospects for industrial applications. The research team for this project was in charged of the design, construction, development and operation of the largest number of shaking tables system in the world: the nine sub-units shaking table array system in the Beijing University of Technology. This system was construction by a Chinese company and was independent development and design domestic. A multi-channels integrated control program for this shaking table array system was developed by the members of this project. The simulation of soil and structure interaction was implemented by transplan
