The invention discloses a blade variable pitch control method and system and an aircraft, the method is applied to a controller, the controller is in communication connection with a first sensor, and the first sensor is mounted at a connecting part of a blade; a controlled part of the paddle is connected with a control end of the variable pitch motor; the paddle variable pitch control method comprises the steps that under the condition that a paddle is in a locking state, a first paddle pitch angle collected by a first sensor is obtained; and under the condition that the first pitch angle is not the abnormal value, the variable pitch motor is controlled to adjust the first pitch angle within the first preset angle range. According to the embodiment of the invention, the pitch angle of the blade is directly acquired through the first sensor mounted on the connecting part of the blade, the real-time pitch angle of the blade can be accurately detected, and the condition that the blade is returned to the mechanical boundary and then subjected to blade pitch change in the state that the blade stops moving is avoided, so that the blade pitch change can be realized in various scenes, and the working efficiency is improved. And the variable pitch requirements of the blades in various scenes are met.

    本发明公开了一种桨叶变距控制方法、系统及飞行器,其中方法应用于控制器,控制器与第一传感器通信连接,第一传感器安装在桨叶的连接部;桨叶的受控部件与变距电机的控制端连接;桨叶变距控制方法包括:在桨叶处于锁止状态的情况下,获取第一传感器采集的第一桨距角;在第一桨距角不为异常值的情况下,控制变距电机将第一桨距角调整在第一预设角度范围内。本发明实施例通过安装在桨叶的连接部的第一传感器直接采集得到桨叶的桨距角,能够精确检测桨叶的实时桨距角,无需要在桨叶停止运动的状态下,将桨叶回顺到机械边界后再进行桨叶变距,从而能够在多种情景下实现桨叶变距,满足多种场景下的桨叶变距需求。
