研究阐述了具有不确定结构参数的两个相邻建筑物在地震激励下的混合控制方法。利用包含原理和具有保证性能控制算法的重叠分散控制策略,提出了一种不确定参数结构系统的重叠分散保性能混合控制算法。基于包含原理,将一个大尺度结构分为一组具有共同部分的成对子结构,其共同部分即重叠的部分。使用保性能算法设计每个成对子结构的控制器,然后利用收缩原理,形成原系统的控制器。将重叠分散保性能混合控制算法应用于具有不确定参数的12层和9层两个相邻建筑物的振动控制问题,并与集中的保性能振动控制方法进行了比较,两种方法下结构层间位移的最大控制率分别为50%~60%和60%~70%。数值结果表明:对于具有不确定结构参数的两个相邻建筑物,该方法可以有效地抑制结构的动力响应,确保控制系统稳定性,提高了控制器设计的灵活性和可靠性。
This paper presents a hybrid control method for two adjacent buildings with uncertain structural parameters under earthquake excitation. By using the principle of inclusion and the superposition decentralized control strategy with guaranteed performance control algorithm, a hybrid distributed and guaranteed hybrid hybrid control algorithm for structural systems with uncertain parameters is proposed. Based on the inclusion principle, a large-scale structure is divided into a group of pairs of sub-structures that have a common part, that is, overlapping parts. Using guaranteed algorithm to design each pair of sub-structure controller, and then use the contraction principle to form the original system controller. The hybrid control algorithm with overlapping decentralized guaranteed functions is applied to the vibration control problems of two adjacent buildings with 12th and 9th floors with uncertain parameters and compared with the centralized guaranteed Vibration control method. The structural layer The maximum control rate between the displacement of 50% to 60% and 60% to 70%. The numerical results show that this method can effectively suppress the dynamic response of two adjacent buildings with uncertain structural parameters, ensure the stability of the control system and improve the flexibility and reliability of the controller design.
