A robust adaptive control design for active tuned mass damper systems of multistory buildings

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.

Automated summary

A robust adaptive controller is designed for damping undesired vibrations on multistory buildings during earthquakes, with adaptive compensation rules and backstepping control design approach utilized. The controller's stability is proven through Lyapunov-based analysis in simulation studies on a nine-story building under a major earthquake.
