The invention discloses an aircraft landing gear folding and unfolding control method and system, and the method comprises the steps: obtaining a folding and unfolding signal of a landing gear; the servo motor is triggered to rotate according to the folding and unfolding signal of the undercarriage; the position information of the in-place switch is monitored, and the rotating speed of the servo motor is adjusted based on the position information of the in-place switch; pressure information of the pressure sensor is monitored, and rotation of the servo motor is stopped based on the pressure information of the pressure sensor; if the pressure information is higher than a preset pressure threshold value and lasts for preset time, rotation of the servo motor is stopped, the landing gear folding and unfolding action is completed, at the moment, the rotation speed of the servo motor is adjusted based on the position information of the in-place switch, the rotation speed of the servo motor is increased or decreased, and the landing gear folding and unfolding action is completed. The stop of rotation of the servo motor is controlled based on the pressure information of the pressure sensor, so that the action of the servo motor is jointly controlled by combining the position information of the in-place switch and the pressure information of the pressure sensor, and regulation and control are carried out in multiple dimensions.

    本发明公开了一种飞机起落架的收放控制方法及控制系统,其中,获取起落架的收放信号;根据起落架的收放信号触发伺服电机的旋转;监控到位开关的位置信息,并基于到位开关的位置信息调整伺服电机的旋转速度;监控压力传感器的压力信息,并基于压力传感器的压力信息停止伺服电机的旋转;若压力信息高于预设压力阈值且持续预设时间,则停止的伺服电机旋转,并完成起落架收放动作,此时,基于到位开关的位置信息调整伺服电机的旋转速度,对伺服电机的旋转速度进行进行提高或者降低,基于压力传感器的压力信息控制伺服电机的旋转的停止,以便于结合到位开关的位置信息和压力传感器的压力信息共同控制伺服电机的动作,从而在多个维度上进行调控。
