Active vibration control of the linear structure with an active mass damper applying robust saturation controller

A robust saturation controller, which involves both control input’s saturation and structured real parameter uncertainties, has been proposed recently. In this paper, this robust saturation controller is applied to the linear structure with an active mass damper. A controller design method of improving control performance of the robust saturation controller is newly proposed based on optimization problem of linear matrix inequality and its availability for the linear structure with an active mass damper is shown through numerical simulations. Furthermore, the applicability of the robust saturation controller is verified through experimental tests in the laboratory for a two-story test structure equipped with a hydraulic-type active mass damper.
