Abstract

In this paper a novel approach to the design of active controllers aimed at reducing vibrations in helicopter applications is proposed. In particular the role of variability in the vibratory response of the helicopter (such as due to, e.g., varying flight condition and actuator nonlinearities) is taken into account in the synthesis of a robust parameter-varying controller, based on a discrete-time LPV model of the system. Numerical examples demonstrate the effectiveness of the proposed approach, in comparison to other classical strategies.
