Robust harmonic control: an application to structural vibration reduction in helicopters

This work addresses the problem of designing robust multivariable controllers for the attenuation of the structural response of a helicopter, with reference to the Agusta A109 helicopter. The considered configuration consists of a set of piezoelectric actuators and accelerometers located on the fuselage of the helicopter. The robust harmonic control approach is adopted, based on an data-driven mathematical model of the system.
