This paper proposes an automatic tuning algorithm for a sliding mode controller (SMC) based on the Ackermann's formula, that attenuates the structural vibrations of a seismically excited building equipped with an Active Tuned Mass Damper (ATMD) mounted on its top floor. The switching gain and sliding surface of the SMC are designed through the proposed tuning algorithm to suppress the structural vibrations by minimizing either the top floor displacement or the control force applied to the ATMD. Moreover, the tuning algorithm selects the SMC parameters to guarantee the following closed-loop characteristics: 1) the transient responses of the structure and the ATMD are sufficiently fast and damped; and 2) the control force, as well as the displacements and velocities of the building and ATMD are within acceptable limits under the frequency band of the earthquake excitation. The proposed SMC shows robustness against the unmodeled dynamics such as the friction of the damper. Experimental results on a reduced scale structure permits demonstrating the efficiency of the tuning algorithm for the SMC, which is compared with the traditional Linear Quadratic Regulator (LQR).

“…Recent developments in structural control engineering have encouraged researchers and engineers to pursue more sophisticated and comprehensive steps to improve the performance of structures, during extreme winds or severe seismic events. [1,2] The use of supplementary energy dissipating devices, which include passive, [3][4][5] active, [6][7][8][9] hybrid, [10][11][12] and semiactive control devices have been implemented in successfully achieving the goal of structural control via different mechanism. It includes the use of friction damper which dissipates the energy generated during a seismic event mechanically through friction, [13,14] restoring force generated by passive and active tuned mass damper (ATMD), [15][16][17][18] yielding of metallic elements by metallic yield devices, [19,20] damping force generated by the viscosity of passive viscous damper, [21][22][23] or the variable viscosity of magnetorheological (MR) fluid produced by MR dampers.…”

The field of semiactive control dampers for structural control has seen a significant advancement in recent years. However, the controllers proposed in recent years have been computationally inefficient, time consuming, and did not allow the designer the flexibility in overall structural control. Consequently, this study presents a sequence of numerical and experimental studies conducted to determine the efficiency and performance of proposed multiple response optimization (MRO)-based control with iterative technique, using magnetorheological (MR) dampers as a control device in mitigating the structural response. The prime objective of the MRO control strategy is selecting an optimal control gain, obtained by a trade-off between the gains corresponding to the local minima of structural responses, selected as the performance objective of the controllers. The proposed strategy is numerically compared with H 2 /LQG with clipped optimal control (COC). Results indicated the efficiency and flexibility of the proposed strategy in mitigating the structural responses. Finally, multiple shake table tests were performed on a five-story steel frame with MR damper, employing the control strategies to be examined. The corresponding results substantiated the superiority of MRO control over passive control strategies, in mitigating the structural responses.

“…However, depending on the parameters of the structure and the ATMD, the energy requirements of the systems used for vibration damping can be quite high. 8,9 This is an undesirable situation in control systems as it may increase the needed control effort. Dyke et al 10 preferred the acceleration feedback controller for structures which use ATMD system for damping the earthquakes.…”

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.
