In recent years, optimal control which minimizes a cost function formulated by weighted
states and control inputs has been applied to the seismic control of structures. Optimal …

The linear-quadratic regulator (LQR) has been applied to structural vibration control for
decades; however, selection of the weighting matrices of an LQR mostly depends on trial …

Active mass dampers (AMDs) have been used to suppress vibration of structures subjected
to dynamic loading. Generally, controller design of AMD requires an identified numerical …

During the past few decades, major structural damages due to natural disasters like
earthquakes has led bridge engineers to develop structural control systems to mitigate …

Earthquakes cause irreparable damages to the built environment, which has led bridge
engineers to develop structural control systems to mitigate damage and improve vibration …

Two novel semi-active control methods for a seismically excited nonlinear benchmark
building equipped with magnetorheological dampers are presented and evaluated in this …

It is realized that force exerted at the two ends of an inerter is proportional to their relative
acceleration between them. Generally, a mechanical inerter has much smaller mass than a …

Vibration and displacement control are of critical importance for both high-rise and ultra high-
rise building systems. A single-floor building-like structure equipped with an active mass …

In the linear quadratic regulator (LQR) problem, the generation of control force depends on
the components of the control weighting matrix R. The value of R is determined while …

This paper aims to present an alternative for modeling an inverse dynamic behaviors of a
magneto-rheological (MR) damper using a Takagi-Sugeno-Kang (TSK) fuzzy inference …
