Abstract

In this paper the problem of active control of vibrations in helicopters is faced in a very general way. Precisely, we consider the case when the aircraft moves according to a possibly varying forward velocity. The problem is then more complex that the one encountered in hover or in forward flight. We tackle the general problem by means of an LPV (Linear Parametrically-Varying) approach, complemented with concepts drawn from LMI (Linear Matrix Inequalities) realm, H₂-filtering and H_∞ control. The simulations indicate that the overall controller so obtained is most promising.
