Adaptive Vibration Control for an Active Mass Damper of a High-Rise Building

Abstract

As a kind of large flexible structure, high-rise buildings need to consider wind-resistant and anti-seismic problems for the safety of occupants and properties, especially in coastal areas. This paper proposes an infinite dimensional model and an adaptive boundary control law for an active mass damper(AMD) on this question. The dynamic model of the high-rise building is a combination of some storeys which have flexible walls and rigid floors under a series of physical conditions. Then the adaptive boundary controller is acted on an AMD which is equipped on the top floor, in order to suppress the vibration of every floor and guarantee the comfort of residents. Moreover, simulations and experiments are carried out on a two-floor flexible building to illustrate the effectiveness of the proposed control strategy.

Iterative Learning Tracking Control for a Vehicle-Manipulator System With Input Constraint

“…To effectively improve working performance of flexible robot manipulator, great efforts have been made to analysis its dynamic model in different working environments and develop efficient vibration attenuation and tracking-control strategies. Until now, there appear a series of methods and theories that are applied broadly in the manipulator research [3]- [8], such as PD control [9], adaptive control [10], and sliding-mode control [11]. In [3], based on a novel Lyapunov function consisting of logarithm function and step function, angle tracking and deformation attenuation issues are solved for a flexible variable-length rotary crane arm under extraneous disturbances.…”
