摘　　要：文章研究了一种建筑结构系统在执行器失效情况下的有限时间稳定振动控制问题.在系统的控制设计中,采用自适应模糊控制的方法,将地震波作为未知的非线性项进行动态补偿,可以有效提高控制性能.此外,提出了自适应故障补偿方法,并结合故障补偿方法设计的有限时间主动振动控制器,能够快速有效地抑制建筑结构振动.在此控制策略下,具有不确定执行器失效的建筑结构系统可以在有限时间内保持稳定.通过在不同失效情况下的仿真结果表明,该方法在有限时间内的抗震有效性优势显著.This paper investigates the finite-time stability vibration control for building structures system in presenting of actuator failures. The approach of dynamic compensation for seismic wave would more effectively improve control performance by considering it as unknown nonlinear item in system. In control design, the item is approximated by adaptive fuzzy control method. In addition, actuator failures would be lessened or even totally lost with the effectiveness suppress for building structure vibration. To handle this problem, an adaptive failure compensation method is proposed. Moreover, in order to rapidly suppress vibration, finite-time active vibration controller is designed by combing failure compensation method. Under the proposed control strategy, building structures system with uncertain actuator failures can be guaranteed stable in finite time. Finally, examples with different failure case are given to demonstrate the anti-seismic effectiveness of the proposed method.
