结构振动主动控制系统对参数不确定性极其敏感，其可靠性估计近年来受到越来越多的关注。针对实际工程中不确定性信息不足的问题，考虑结构参数未知但有界的不确定性，提出一种将主动振动控制理论与区间分析相结合的非概率瞬态可靠性方法，以有效估计受控结构的动态安全性。首先分析了基于闭环控制的不确定结构响应，并用区间过程模型来体现。借助第一通道理论，对结构振动主动控制系统进行非概率瞬态可靠性分析的积分过程。最终提出了两个工程实例和一个实验应用，以证明所开发方法的有效性和适用性。
The active control system for structural vibration is extremely sensitive to the parametric uncertainty so that more and more concerns of its reliability estimation have been given recently. In view of the insufficiency of the uncertainty information in practical engineering, a non‐probabilistic time‐dependent reliability method that combines the active vibration control theory with interval analysis is proposed in this paper to effectively estimate the dynamic safety of the controlled structures, in which circumstances the unknown‐but‐bounded uncertainties in structural parameters are considered. The uncertain structural responses based on the closed‐loop control are firstly analyzed and embodied by the interval process model. By virtue of the first‐passage theory, an integral procedure of non‐probabilistic time‐dependent reliability analysis of the active control system for structural vibration is then conducted. Two engineering examples and one experimental application are eventually presented to demonstrate the validity and applicability of the methodology developed.
