摘要

摘要: 根据线性最优主动控制的原则,提出了同时控制位移、速度和加速度的最优主动控制策略,导出了修正Riccati方程。由此利用磁流体阻尼器,对巨型框架多功能减振结构的脉动风振反应进行了半主动控制,表明该结构体系的半主动控制比被动控制能更显著地减小主、次框架的振动加速度,能更有效地降低主框架的振动位移。

Abstract: Based on the principles of linear optimal active control, this paper develops an optimal active control algorithmcommanding the structure displacement, velocity and acceleration simultaneously, and derives the revisal Riccati equationfrom this. Moreover, the semiactive control has been used for the pulsating wind vibration response of multifunctionalvibration -absorption megaframe structure by means of magnetorheological damper. The result seems to indicate that the sem-iactive controlmay be able to more significantly reduce the vibration acceleration response of the main and the secondaryframes, and to more effectively suppress the vibration displacement response of the main frame than the passive control.
