“…13 In Ref. 14, Shan et al proposed model reference adaptive control to reduce the effect of earthquake to excited structures. The adaptive control law is developed based on backstepping theory and the stability of controlled system was analyzed considering a little prior knowledge of structural model and parametric effects due to actuator saturation and the switching delay.…”

In this study, the design of adaptive backstepping sliding mode control (ABSMC) has been developed for vibration suppression of earth-quaked building supported by magneto-rheological (MR) damper. The control and adaptive laws developed based on ABSMC methodology has been established according to stability analysis based on Lyupunov theorem. A Single degree of freedom (SDOF) building system has been considered and the earthquake acceleration data used in performance analysis of the proposed controller is based on El Centro Imperial Valley Earthquake. The ABSMC has been compared to classical sliding mode control in terms of vibration suppression in the controlled system subjected to earthquake. The performance of proposed controller has been assessed via computer simulation, which showed its effectiveness to stabilize the building against earthquake vibration and the boundness of estimated stiffness and viscosity coefficients.

“…In addition to the mentioned studies, negative acceleration feedback control, 20,21 optimal sliding mode control, 22 and fuzzy sliding mode control 23 were also used for this control purpose in recent years. In vibration control applications, the backstepping controller and Lyapunov-based controllers are widely used with magnetorheological dampers [24][25][26] and active base isolator systems 27 as well as ATMD systems.…”

Summary The design of a novel backstepping controller for using with active tuned mass damper (ATMD) system is investigated in this study. The main aim of this study is to design the controller for the ATMD system to reduce earthquake‐induced vibrations in multistory buildings. Obtaining a generalizable control design for such systems is another important aim of this study. To reach this aim, the designed controller is based on the assumption that the system parameters are completely uncertain. The parametric uncertainty is coped with via adaptive compensation rules proposed in accordance with available system states. Effects of the control force on the displacement of the controller mass and the last floor of a multistory building are considered together. Owing to this approach, a control operation is provided in which zero convergence of the displacement of the mass of ATMD and all floors of the building can be guaranteed. Using Lyapunov‐based arguments, theoretically, it has been proven that the designed controller can maintain its stability of the structure and controller mass while achieving this main control objective. The efficiency of the designed controller in terms of reaching the mentioned control objective is observed via numerical simulations. In these simulations, the designed controller is used in conjunction with an ATMD system placed on a multistory building model, and it has been shown that the controller designed in such structures can be used effectively for damping the earthquake‐induced vibrations of these types of structures.

“…In the aforementioned structure, the vibration of a nine-story building exposed to an earthquake was tried to be damped via a Lyapunov-based adaptive control design based on the backstepping control approach. The use of the backstepping controller with ATMD systems for reducing vibration of buildings is very limited in the literature, but it is possible to find examples of use with magnetorheological dampers (Ali and Ramaswamy, 2009;Ouyang et al, 2019a;Shan et al, 2018;Zapateiro et al,2009) and active base isolators (Ouyang et al, 2019b;Pozo et al, 2006). In some studies (Amini and Ghaderi, 2013;Ghaderi and Amini, 2017), earthquake-induced vibrations were dampened by applying force to the multiple floors of the building, with actuators placed in another rigid structure by using the backstepping controller.…”

In this study, a robust adaptive controller is designed to be used in an active tuned mass damper system that can be used to damp undesired vibrations that occurred on the multistory buildings during the earthquake. To realize the controller design, all of the system parameters are assumed to be unknown, and the adaptive structure of the designed controller is obtained by designing adaptive compensation rules for system parameters. A backstepping control design approach is utilized for the control design by considering the appropriateness of the system’s structure of multistory buildings having an active tuned mass damper system at the top of the structure. The proposed control design is supported with a Lyapunov-based stability analysis where it is proven that the designed controller is able to protect the overall system’s stability while reaching the main control purpose. In addition to these, in the simulation studies realized for a nine-story building under the effect of a major earthquake, it is shown that the designed controller can be used to reach the main control purpose efficiently.
