TL;DR: In this article, a robust sliding mode control (SMC) approach is presented for vibration control of wind-excited high-rise building structures, where a low pass filter is properly selected to remove the high-frequency components of the control force while retaining the structural stability.
Abstract: A robust filtered sliding mode control (SMC) approach is presented for vibration control of wind-excited highrise building structures. Rather than using a Lyapunov-function based control design, an alternative way is provided to find the control force based on the equivalent control force principle to obtain the control force. A low pass filter is properly selected to remove the high-frequency components of the control force while retaining the structural stability. The performance of the proposed filtered SMC is evaluated by application to a wind-excited 76-story building benchmark problem equipped with an active tuned mass damper (ATMD) on the roof. Due to the elimination of high-frequency part of the control force, the structure, sensors, actuators, and dampers are all less excited, and consequently their response is reduced compared with the unfiltered SMC approach. In addition, the required control forces are reduced which means a reduction in the size of actuators, thus making their implemen...

TL;DR: In this article, a passive system of vibration protection, which combines principles of vibration isolation and dynamic absorption, can be effectively used in hand-held percussion machines, where the vibration isolator between the handle and the casing of the machine reduces the highfrequency components of acceleration perceived by an operator.

TL;DR: In this paper, a three-sided membrane with inwardly curved edges and uniform tension was transmitted by thin steel cables encased in the edges, and the first few vibration modes measured in a near vacuum were shown to be predictable by finite element structural analysis over a range of applied tension loads.
Abstract: Vibration studies carried out in a vacuum chamber are reported for a three-sided membrane with inwardly curved edges Uniform tension was transmitted by thin steel cables encased in the edges Variation of ambient air pressure from atmospheric to near vacuum resulted in increased response frequencies and amplitudes The first few vibration modes measured in a near vacuum are shown to be predictable by a finite element structural analysis over a range of applied tension loads The complicated vibration mode behavior observed during tests at various air pressures is studied analytically with a nonstructural effective air-mass approximation The membrane structure is a candidate for reflective surfaces in space antennas

TL;DR: In this paper, a SMA-based oscillator is proposed to absorb the vibration energy input into the primary system, and the performance of the SMA oscillator at high temperatures is close to that of a linear oscillator, while at low temperatures it behaves as a regular damper.
