Abstract

[en] This thesis proposes a novel method for the design of five decentralized Positive PositionFeedback controllers in order to reduce the resonant peaks of a bladed rail structure. Themodel is based on the root-locus analysis from which an algorithm is derived by consideringthat maximum damping occurs when the poles of closed-loop are merged together. Theparameters for the controllers are derived using theH2optimization technique. This modelis first used for single-mode damping then, it is extended to multi-mode. The controllersare applied on a numerical model and by experiments. Subsequently, some controllers arereplaced by electric shunt circuits in order to reduce the power consumption of the activedamping technique. Purely resistive as well as resonant shunts are investigated on a numericalmodel. The resistive circuit is also testes experimentally.
