摘要：AbstractThis work addresses the identification of a control-oriented multivariable model of the structural response of a helicopter, with reference to the Agusta A109 helicopter. The estimated model will be used to design an active vibration control system to reduce the vibrations transmitted to the cabin by the main gearbox. The considered system consists of a set of piezoelectric actuators mounted at the interface between the gearbox and the cabin and accelerometers located on the cabin roof. Identification data are generated by independent excitation of each individual actuator. Model identification is carried out using a subspace identification algorithm.
