为了解决调谐质量阻尼器(TMD)的有效工作频域较窄和主动质量阻尼器(AMD)的控制力存在时滞效应的问题,提出在 TMD 中嵌入磁流变阻尼器(MRD)的新型半主动控制装置———TMMRD。采用模糊控制器取代传统滑动模态控制(SMC)的不连续“开关”式控制和等效控制的不确定性规则,基于 Lyapunov 函数设计自适应模糊控制律,结合改进的限幅最优(MCO)控制算法提出适合 TMMRD 的自适应模糊滑动模态半主动控制(ASMC/ MCO)策略。运用 TMD 被动控制、ASMC/ MCO 半主动控制、ASMC 主动控制和线性二次型高斯(LQG)主动控制分别对一座30层钢框架结构进行地震响应分析。研究结果表明:提出的 ASMC 控制策略的鲁棒性明显优于 LQG;ASMC/ MCO 控制和 ASMC 控制下的减震效果明显优于 TMD 控制和 LQG 控制;ASMC/ MCO 的半主动控制力与 ASMC 的主动控制力吻合很好。

A new semi-active control device TMMRD, which was constructed by embedding the magneto-rheological damper (MRD) into tuned mass damper (TMD), was proposed, in which the problems of both narrow frequency-domain of effective work in TMD and time-lag of control force in active mass damper (AMD) could be solved well. The discontinuous switching type of control laws of traditional sliding mode control (SMC) and uncertainty terms of equivalent control were replaced by fuzzy controller, the adaptive fuzzy control law based on the Lyapunov function was designed, the adaptive fuzzy sliding mode control (ASMC) was integrated with a modified clipped optimal (MCO) control algorithm, and then the semi-active control strategy ASMC/ MCO for TMMRD was proposed. The seismic responses of a 30-storey steel frame structure with TMD, ASMC/ MCO semi-active controller, ASMC active controller and linear quadratic Gaussian ( LQG) active controller were computed, respectively. Computation results indicate that the robustness of ASMC controller is obviously superior to that of LQG controller. The reduction effects on seismic responses under ASMC/ MCO control and ASMC control are obviously supe-rior to those of TMD control and LQG control. The control force of ASMC/ MCO controller is almost the same as that of ASMC controller.
