Reduced-order robust controller design for vibration reduction
Tijdschriftbijdrage - Tijdschriftartikel Conferentiebijdrage
Active vibration reduction for lightweight structures has attracted more and more attention in automotive industries. In this paper, reduced-order controllers are designed based on H∞ techniques to realize vibration reduction. A finite element model of piezo-based smart structure is constructed from which a nominal model
containing 5 modes and validation model containing 10 modes are
extracted. A mixed-sensitivity robust H∞ controller is firstly designed
based on the nominal structural model. Considering the ease of
controller deployment, an order reduction for the controller is then
exploited using balanced truncation method. The effectiveness of the
reduced-order controller is finally verified on the validation model via
system simulations.
