A coupled robust control optimization approach for active-passive hybrid adaptive structures

Abstract: The active-passive hybrid piezoelectric network (APPN) has been shown to be very effective in structural control. However, the issue of robustness of such configurations has yet to be investigated. To ensure that the APPN concept still performs well under uncertainties, a coupled robust control/optimization approach is proposed to determine the active and passive parameters simultaneously with the consideration of system uncertainties. Analysis is also performed to gain insights.
