中文摘要：
对于建筑结构主动控制系统，传感器或执行器在实际工程中可能会出现故障而失效，这将严重影响结构的减震效果。针对AMD建筑结构系统传感器出现故障的情况，基于AMD建筑结构模型，提出建筑结构主动控制系统的故障诊断与隔离技术（faultdetectionandisolation，FDI），设计基于容错控制技术（faulttolerantcontrol，FTC）的主动容错控制器。将FDI和FTC的设计过程转化为H∞控制问题，利用变量替换法推导线性矩阵不等式（1inearmatrixinequality，LMI）凸约束，通过LMI算法解算出结果。最后通过带有AMD装置的三层框架结构数值算例，考虑位移传感器出现故障而失效，应用故障检测隔离技术，设计容错控制器，并且验证故障检测隔离技术和容错控制的有效性。
英文摘要：
In the civil structures with AMD control system, the sensors or actuators may work bad or even lose their performance, which can worsen the vibration suppression. Considering the sensors with faults in AMD control system of the civil structural model, this paper presents fault detection and isolation （FDI） and fault tolerant control （FTC）. The FDI filter and FTC controller are designed based on H ∞ control schemes and computed by solving linear matrix inequality （LMI） problem with convex constrains. Through an example of three-story structure numerical with AMD control system, FDI filter and FTC controller are designed considering the fault of displacement sensors. The results validate the efficiency of FDI and FTC.
