This paper presents a simultaneous optimization approach to the design of the multiple active tuned mass damper (MATMD) and its controller for building vibration attenuation under seismic excitations. A model of an n‐storey building installed with the MATMD system, where the masses can be placed on different storeys, is considered, and its state‐space model is established by appropriately defining the state variables and the output signals. Considering that earthquake records exhibit higher strength over a certain range of frequency and the fact that not only the controller design but also the parameter optimization of the MATMD system have significant effects on the control performance, a simultaneous optimization approach based on the genetic algorithm (GA) is proposed to design the static output‐feedback controller and to obtain the MATMD's parameters for the attenuation of seismic building vibration over a finite frequency range. Using the proposed approach, a set of parameters and the constrained controller gains, which can guarantee the asymptotic stability of the closed‐loop system and attenuate the building vibration at a sufficiently low level, are obtained. Simulations are used to demonstrate the effectiveness of the proposed approach and the superiority of a strategy that places the masses on different storeys in attenuating building vibration under earthquake excitation.

International audienceAn active vibration control system using an inertial actuator will be used to assure the vibration isolation of a chassis in the presence of multiple unknown time varying tonal vibrations located in two distinct regions in the frequency domain. The objective is to minimize the residual force by applying an appropriate control effort through the inertial actuator. The system does not use any additional sensor for getting in real-time information upon the disturbances. A hierarchical feedback approach will be used for the control of the system. At the first level a robust linear controller will be designed taking advantage of the knowledge of the domains of variation of the frequencies of the vibrations. However the performance of the linear controller is somehow limited because of the width of the regions of variation of the frequencies of the vibrations and the robustness constraints. To further improve the performance, a direct adaptive control algorithm will be added. Its design takes into account the internal model principle for disturbance rejection and is conveniently implemented through the Youla-Kučera parametrization of the controller. Experimental results obtained on a relevant test bench will illustrate the methodology

“…A piezoelectric material with good electromechanical coupling, frequency response, and reliability is one of the most attractive smart structures for structural vibration control [3]. In real multimode piezoelectric structural vibration control framework, the whole system always faces with different undesirable characteristics, such as strong interactions among the variables, complex dynamic features, output superposition, and strong external disturbances [14]. To improve the vibration suppression ability of the piezoelectric structure, the feedforward compensation design for disturbances is usually considered.…”

“…To solve these problems, two kinds of disturbance estimation methods have been well developed to facilitate the design of such composite control methods. One is the disturbance observer technique, which is originally proposed by Ohnishi et al [15], and has been widely applied to different systems, e.g., missile systems [16], hard-disk-drive systems [17], humanoid joint [18], general motion control systems [19], [20], structural vibration control systems [14], [21], [22], and so on.…”

Considering the variety of uncertainties and disturbances in real active vibration control systems, a novel piezoelectric multimode control strategy for an all-clamped stiffened plate (ACSP) structure is proposed in this paper. First, an active disturbance rejection control (ADRC) method, i.e., the extended state observer (ESO)-based vibration control scheme, is employed to ensure the performance of the vibration suppression and rejection of the lumped disturbances of the closed-loop system. Second, a proportional differential controller and an acceleration feedforward controller produce the control law for each vibration mode. Moreover, a chaos optimization method based on a logistic map is introduced to automatically tune the parameters of the feedback channel. The stability and superiority of the proposed controller are theoretically analyzed. Compared with the classical ADRC method, the multimode vibration experimental results demonstrate that the control performance of the first mode is improved from 12.04 to 14.06 dB; meanwhile, the performance of the second mode is also improved, having changed from 11.1 to 13.68 dB.
