Abstract

The individual blade control of bearingless composite helicopter rotors aiming at vibration attenuation using adaptive structures is studied in this paper. A periodic model-following regulator is developed in the frequency domain to approximate the aeroelastic response of a single blade in forward flight to its hover characteristics. Two control strategies are investigated: a more robust one using distributed control, and a more cost-efficient one using lumped control. Selective linearization of the periodic system at determined frequencies is demonstrated in both cases.
