摘要
传统集中式控制方法需同时采用系统所有测量信号，进而计算出所有作动器的控制力并发出信号进行振动控制，其控制系统复杂且可靠性较差。近年来出现的基于系统局部信息反馈的分散控制策略，设计简单及可靠性高，已经成为目前研究的热点之一。目前分散控制策略的作动器控制力仅采用建筑物的相邻两层测量信号进行控制，虽然能够控制住结构的响应，但信息过少，控制效果不好。为了达到更好的控制效果，在鲁棒控制策略的基础上，通过设置特殊矩阵的方式，提出了一种基于建筑物相邻四层信号的鲁棒分散控制方法。从动力仿真的结果来看，本文方法的控制效果比仅依靠相邻二层信号的控制效果好得多。
Abstract
The traditional control methods which are considered as centralized ones have to measure all signals simultaneously and than the whole control ability of actuator can be calculated and the signals can be sent out for vibration control. These methods have complex control system and poor reliability. In recent years, the decentralized control strategy based on the feedback of partial state has simple design and high reliability, and it has become the hot hit of resent research. Nowadays, the control ability of actuator is controlled just by using the measured signal of a building’s two interfacing floors. Although it can control the response of structure, the information is too less and the control performance is not good yet. As a result, basing on the robust control strategy and by setting up special matrix, a robust decentralized control method based on the measured signal of a building’s four interfacing floors has been proposed. And from the performance of dynamical simulation, the control performance of proposed method is much better than the one which depend on the signal of two interfacing floors at the same control ability.
