Abstract: In view of the control theory, this paper interprets the basic principles of higher harmonic control(HHC) and proposes the mathematical models of the rotor and of airframe vibration, as well as the methods for identification of parameters. A higher harmonic controller is designed and the results of numerical simulation show that the vibration level is reduced effectively.

Key words: helicopters vibration, harmonics active control
