斜铰旋翼操纵力矩生成研究

Research on the Moment Generation of Tilt-hinge Rotor

为了对无人旋翼飞行器使用的斜铰旋翼进行深入研究,提出基于旋翼转角反馈的转速调节规律和基于滞后角的操纵力矩方向控制方法,仿真结果表明斜铰旋翼按该转速调节规律运行能够形成可自由调节的操纵力矩。考虑斜铰旋翼在实际应用中可能出现的转速变化,将其作为仿真输入,仿真结果表明斜铰旋翼能够快速响应转速变化,且当前工作状态对于斜铰旋翼后续运行影响较小,能够满足使用需求。

With the focuse on the generation of the control moment of tilt-hinge rotor,a speed regulation law based on the rotation angle feedback and the control law for moment direction based on the lag angle were proposed initially.The simulation result shows that generated moment can be changed as wished under the speed regulation law.The possible mode of rotor speed in practical application then was applied as simulation input to see its influence on the rotor,with the result further indicating that tilt-hinge rotor can respond to the change of rotor speed quickly and the current operating state has little influence on the subsequent operating state of the rotor meeting the unmanned helicopter’s requirement.
