“…The two damper masses are driven by servo-hydraulic actuators [ 74 ]. Elias et al [ 115 ] showed that the performance of the active controllers for vibration control of buildings subject to pulse-type ground motions is not significant. Plus, the assumption of elastic models is not realistic.…”

Since the early ages of human existence on Earth, humans have fought against natural hazards for survival. Over time, the most dangerous hazards humanity has faced are earthquakes and strong winds. Since then and till nowadays, the challenges are ongoing to construct higher buildings that can withstand the forces of nature. This paper is a detailed review of various vibration control strategies used to enhance the dynamical response of high-rise buildings. Hence, different control strategies studied and used in civil engineering are presented with illustrations of real applications if existing. The main aim of this review paper is to provide a reference-rich document for all the contributors to the vibration control of structures. This paper will clarify the applicability of specific control strategies for high-rise buildings. It is worth noting that not all the studied and investigated methods are applicable to high-rise buildings; a few of them remain limited by many parameters such as cost-effectiveness and engineering-wise installation and maintenance.

“…30 Based on the concepts outlined above, a control system formed of springs and an inertial mechanism, whose principle of operation was based on the proportionality of applied forces, has been studied for suppressing the vibration of beams under moving loads. 31 Control systems based on applied forces have also been assessed by simulating a pulse-type ground motion, 32 they have been treated numerically by considering a hydraulic system with variable inertia (e.g., a valvecontrolled power hydraulic system as a vibration isolator) 33 and experimentally by employing a jack as a control device. 34 In addition, hydraulic jacks with variable stiffness have been computationally assessed for use as control devices to attenuate the displacement of a building under seismic action.…”

The aim of this work was to assess the capability of a hydraulic bottle jack to control vibrations and the effects of earthquakes. The first stage of the present investigation focused on determining the axial stiffness of the apparatus, in order to relate its behavior to that of a linear elastic element. To do this, uniaxial compression tests were carried out using a manually controlled servo system. In the second stage, a conceptual application based on the field of mechanical vibrations was considered. The experimental results confirmed the hypothesis of linear behavior and showed that the stiffness coefficient had distinct values of magnitude that depended on the cylinder height. Simulations were conducted in which the frequencies and the peak displacements of an idealized SDOF system subjected to earthquake excitation were adjusted based on the experimental stiffness. It was possible to conclude that the equipment analyzed here is an effective tool for controlling vibration and reducing displacement during a seismic event, and can be calibrated according to the specific conditions of operation. This is an important aspect of safety and functionality for mechanical and structural systems.

“…Intelligent controllers are not confined to neuro-fuzzy systems. Brain emotional learning-based intelligent controller (BELBIC) has been applied on various systems and satisfactory results have been obtained (Debnath and Mija, 2023; Elias et al, 2023; Tao et al, 2023; Yazdani et al, 2018). It is based on the computational model of a limbic system in the human brain.…”

In this paper, an adaptive controller for a class of uncertain nonlinear systems is presented using a combination of Legendre polynomials and brain emotional learning-based intelligent controller (BELBIC). Recently, some versions of BELBIC have been presented with the aim of satisfying the universal approximation property using Gaussian basis function. However, the size of regressor vector is too large that imposes a heavy computational load to the processor. The novelty of this paper is presenting a new version of BELBIC with less computational burden using Legendre polynomials. Moreover, there are very few tuning parameters in Legendre polynomials. Another contribution of this paper is editing the stability analysis presented in recent related works. Due to the intrinsic non-differentiability of the adaptation rules of BELBIC, the second time derivative of Lyapunov function is undefined and thus, the Barbalat’s lemma cannot be applied to verify the asymptotic convergence of the error function. Therefore, bounded-input-bounded-output (BIBO) stability can only be claimed for this controller. Simulation results on different case studies show that Legendre polynomials can improve the universal approximation property of BELBIC with less tuning parameters. Moreover, in the absence of the robust control term in the control law, the performance Legendre polynomials will not deteriorate, while the performance degrade in Gaussian basis function is quite considerable.
