HELICOPTER VIBRATION REDUCTION TECHNIQUE WITH HARMONIC ACTIVE CONTROL

从控制的观点阐述高次谐波控制（ＨＨＣ）基本原理，提出ＨＨＣ旋翼数学模型；机体振动数学模型；ＨＨＣ参数辨识；

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.
