【Abstract】 Active control of helicopter ‘air and ground resonance’ is a newly developing technology with great potentiality. At present there are two kinds of control approaches: by blade pitch and by trailing edge flap. The theoretical research work in this field is summarized and commented in the paper, such as the mechanism of control, mathematical model, the control law and its design method. The problems and the trends of active control technology for controlling such dynamical stability problem are pointed out, and our points of view are expressed at last.更多还原
