摘要
直升机旋翼所处的复杂气动环境使它遭受复杂的振动 ,引起桨毂交变载荷 ,进而激起机体振动。智能旋翼是目前国际直升机界的一个研究热点。本文以减小桨毂交变载荷为控制目的 ,提出了在线训练神经模拟器的智能旋翼频域神经控制 ,进行了计算机仿真 。
Helicopters suffer from severe vibrations because of the unsteady aerodynamic environment in which the flexible main rotor blades operate. Smart rotor has been a hot research point for active vibration control of helicopter in recent years. In this paper, for the purpose of suppressing alternative loads of blade hub, a neural control method with on line training in frequency domain for the smart rotor is put forward. Calculations for the smart rotor system model show the better stability and robustness of the presented method.
