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

Abstract

In this paper, the robust control of a real high-rise tower is studied, using a newly proposed, in the structural control field, Robust Model Predictive Control scheme (RMPC). Two RMPC controllers were designed considering either displacement mitigation (RMPC 1 ) or power consumption efficiency (RMPC 2 ).The two controllers were compared to the benchmark, robustness-wise, H ∞ control scheme to demonstrate their relative performance. A number of stiffness and damping uncertainty scenarios were designed based on a broad study of the relevant literature, in order to estimate the robustness of each of the three controllers. In all scenarios, variable actuator uncertainty of AE5% was introduced. It was found that all controllers are effective in controlling the tower and demonstrate robustness against parametric and actuator uncertainties with different relative merits over each other. Indicatively, when considering root-mean-square (RMS) and peak displacement and acceleration reduction, the H ∞ had an average performance reduction of 24%, the RMPC 1 31% and the RMPC 2 28% against their uncontrolled equivalent.

Review of Vibration Control Strategies of High-Rise Buildings

“…To illustrate the efficiency of vibration control devices deployed in high-rise buildings, a review of various results obtained and presented in the literature is resumed in the two following tables [ 211 , 212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 ]. Table 1 presents the results obtained when submitting high-rise benchmark buildings to earthquake excitation while equipping them with different control devices (best performances), and Table 2 shows the results of the same high-rise buildings submitted to wind excitations.…”

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

“…It was found that the hybrid control method was efficient on limiting the peak acceleration of the long-span footbridge (case-study) within the serviceability limit to avoid human discomfort. Koutsoloukas et al (2022a) investigated the performance of an ATMD for the vibration control of a real high-rise tower. For the control law of the system, the authors derived a robust model predictive control (RMPC) algorithm.…”

“…The performance of the system was investigated during the Super Typhoon Hato and it was proven efficient for the vibration mitigation of the tower. Koutsoloukas et al (2022b) investigated the performance of the reinforcement learning deep deterministic policy gradient (DDPG) algorithm for the vibration dissipation of a real high-rise tower using an ATMD. The performance of the DDPG was compared to a PTMD and to a LQR.…”

Seismic control of a smart structure with semiactive tuned mass damper and adaptive stiffness property

“…To improve the seismic protection effect of a passive TMD, an active TMD with an actuator and direct power input to the primary structure is developed 28 . Though it has a better control effect, an active TMD will cost lots of power assumption and has a stability problem 29,30 . Compared to the active TMD, a semiactive TMD (STMD) with variable parameters needs less power assumption and has the advantage of inherent stability 31 .…”
