在这份报纸,在系统连接了到一座大楼的邻近的层次的活跃控制的力量的特征被分析。下列特征被观察:(1 ) 活跃控制能提供显著地优异的补加的抑制给一座大楼,但是引起小频率移动;(2 ) 线性二次的管理者(LQR ) 基于控制力量在然而,抑制力量与全部的控制力量几乎相同的地方,由一个有弹性的恢复力量部件和一个抑制力量部件组成有弹性的恢复力量是很小的;并且(3 ) 活跃控制力量大部分时间在全部控制过程期间阻止运动。这三个特征暗示连接到一座大楼的邻近的层次的活跃控制系统与可调节的参数象被动抑制设备一样表现,也就是在活跃控制抑制特征,它是半活跃的控制设备过去常作为活跃控制系统到达类似的性能的机制。二个索引被定义抑制确定在活跃控制系统的控制力量的特征。这二个索引能也被用来确定半活跃的控制到的能力完成活跃控制的表演。基于上述观察,二个原则为半活跃的控制设备和被动 dampers 的参数的优化被成立。第一是要设计的一台半活跃或被动的设备的最大的产量力量与一台活跃设备相同,叫的鈥渄e 符号原则鈥吗?当一样的最大的产量力量被使用时,其它是反应等价物原则,它声明有半活跃或被动的设备的一座大楼的反应与与活跃设备一样。为半活跃的控制设备和被动 dampers 的设计过程详细被描述。最后,二个基准问题的数字模拟被进行表明活跃控制的抑制特征并且调查半活跃的控制的能力完成象活跃控制的一样的表演。
In this paper, the characteristics of forces in active control systems connected to adjacent levels of a building are analyzed. The following characteristics are observed: (1) active control can provide significantly superior supplemental damping to a building, but causes a small frequency shift; (2) the linear quadratic regulator (LQR)-based control force is composed of an elastic restoring force component and a damping force component, where the damping force is almost identical to the total control force, however, the elastic restoring force is very small; and (3) the active control forces prevent mction most of the time during the entire control process. These three characteristics imply that active control systems connected to adjacent levels of a building behave like passive damping devices with adjustable parameters, namely damping characteristics in an active control, which is the mechanism used by semi-active control devices to reach similar performance as active control systems. Two indices are defined to quantify the damping characteristics of control forces in active control systems. These two indices can also be used to quantify the capacity of semi-active control to achieve the perfonrlance of active control. Based on the above observations, two principles are founded for optimization of parameters of semi-active control devices and passive dampers. The first is that the maximum output force of a semi-active or passive device to be designed is identical to an active device, called "design principle". The other is the response equivalent principle, which states that the response of a building with semi-active or passive devices is the same as with active devices when the same maximum output force is applied. The design procedure for semi-active control devices and passive dampers is described in detail. Finally, numerical simulations of two benchmark problems is conducted to demonstrate the damping characteristics of active control and investigate the capacity of semi-active con
