title = "Active vibration suppression of bwb airplane using smooth switching lpv control",
abstract = "In this paper, smooth-switching LPV (Linear Parameter-Varying) dynamic output-feedback (DOF) control is applied to vibration suppression of a Blended-Wing-Body (BWB) airplane wing. For the reduced-order LPV model with divided flight speed envelop subregions, mixed Input Covariance Constraint (ICC) and H∞ LPV controllers are able to robustly suppress bending displacements using hard-constrained control surfaces, and achieve smooth-switching between adjacent controllers. The control design problem is formulated into convex optimiza-tion, which minimizes a combined cost of system output H2 performance and smooth-switching index, subject to a set of Parametric Linear Matrix Inequalities (PLMIs) derived from stability and performance criteria. In addition, a tunable weighting coefficient is introduced in the cost function that provides an optimal design trade-off between system H2 performance and switching smoothness, and therefore the optimal-balanced smooth switching LPV controllers can be obtained.",
