The invention discloses an aircraft propeller wireless variable pitch control system and method. The system comprises a control panel, a controller, a coupling coil assembly, an electric steering engine, an angle sensor, a rechargeable battery, a battery state sensor, a high-frequency signal generation module, a fuselage battery and a high-frequency oscillator. According to the control system and method provided by the invention, the electric steering engine is adopted to provide variable pitch power for the variable pitch execution mechanism, information such as the angle, the speed and the temperature of actual rotation of the electric steering engine can be reflected through feedback information of the electric steering engine, and the controller can accurately adjust the output control signal according to the feedback information of the electric steering engine; therefore, the rotation angle of the electric steering engine is adjusted, the variable-pitch error of the propeller is reduced to the maximum extent, and the variable-pitch precision is improved.

    本发明公开了一种飞机螺旋桨无线变距控制系统及方法,所述系统包括控制面板、控制器、耦合线圈组、电动舵机、角度传感器、可充电电池、电池状态传感器、高频信号发生模块、机身电池、高频振荡器;本发明提供的控制系统及方法,采用电动舵机为变距执行机构提供变桨动力,通过电动舵机的反馈信息可反映电动舵机实际转动的角度、速度、温度等信息,控制器根据电动舵机的反馈信息可精确调节输出的控制信号,进而调节电动舵机转动的角度,最大程度上减少螺旋桨的变距误差,提高变距精度。
