The invention belongs to the technical field of flight control, and particularly relates to an airplane dual-drive control surface single actuator unhooking fault monitoring method and device. The method comprises the following steps: S1, acquiring a first actuator position and a second actuator position fed back by two actuators for controlling a control surface on one side of an aircraft; s2, two actuator positions fed back by two actuators for controlling the control surface on the other side of the aircraft are obtained, and correction is carried out through preset correction coefficients so as to obtain the position of a third actuator and the position of a fourth actuator; and S3, comparing the positions of the four actuators in pairs, determining the position of the other actuator deviating from the positions of the three actuators through a preset error threshold, and taking the corresponding actuator as the actuator with the unhooking fault. A control surface position sensor is omitted, the weight of the system is reduced, and the reliability of the system is improved.
本申请属于飞控技术领域,特别涉及一种飞机双驱动舵面单作动器脱钩故障监控方法及装置。该方法包括:步骤S1、获取对飞机一侧的舵面进行控制的两个作动器反馈的第一作动器位置及第二作动器位置;步骤S2、获取对飞机另一侧的舵面进行控制的两个作动器反馈的两个作动器位置,并通过预设的修正系数分别进行修正,以获得第三作动器位置及第四作动器位置;步骤S3、对四个作动器位置进行两两比较,通过预设误差门限确定偏离其中三个作动器位置的另一个作动器位置,将其对应的作动器作为具有脱钩故障的作动器。本申请取消了舵面位置传感器,减轻了系统的重量,提高了系统的可靠性。
