Control design for seismically excited buildings: sensor and actuator reliability

Abstract

SUMMARYIn this paper we present control design methods that provide desirable levels of performance and simultaneously account for actuator and sensor reliability (or malfunction) for buildings under seismic excitations. Performance is de"ned in terms of the disturbance attenuation (i.e.¸ gain) from the disturbances to the controlled outputs of the system. The reliability of actuators and sensors refers to the deviation of actual control forces or actual sensor measurements from their ideal levels. Simulation results for a six-storey building are used to demonstrate the e!ectiveness of the control analysis and design method presented.

Passive, semi-active, active and hybrid mass dampers: A literature review with associated applications on building-like structures

“…Moreover, the use of the disturbance observer can be found in the control scheme of Nyawako et al (2016). Alt et al (2000) reported that, during an earthquake, the measured signals from the sensors may deviate from the real ones and this could result to a detrimental effect on the controlled structure.…”

Reliable overlapping control for civil structures

“…The lower subsystem is composed of floors 1-12, while the upper subsystem is composed of floors [8][9][10][11][12][13][14][15][16][17][18][19][20]. The overlapping appears in the part of the columns between the 8th and the 12th floors.…”

Robust structural control of a real high‐rise tower equipped with a hybrid mass damper

“…[ 44,45 ] Additionally, it is often that the actuators installed on structures are only periodically inspected/calibrated leading to poor performance. [ 46 ] The actuator uncertainty could be associated with instability and poor control performance [ 44,45 ] thus, it is crucial to also consider its effect within the simulation process.…”

[46] The actuator uncertainty could be associated with instability and poor control performance [44,45] thus, it is crucial to also consider its effect within the simulation process. This work is structured as follows: Sections 1.1 and 1.2 include an extended review of studies which dealt with parametric and input uncertainty, respectively.…”
