In an embodiment, a rotorcraft includes: a flight control computer configured to: receive a first sensor signal from a first aircraft sensor of the rotorcraft; receive a second sensor signal from a second aircraft sensor of the rotorcraft, the second aircraft sensor being different from the first aircraft sensor; combine the first sensor signal and the second sensor signal with a complementary filter to determine an estimated vertical speed of the rotorcraft; adjust flight control devices of the rotorcraft according to the estimated vertical speed of the rotorcraft, thereby changing flight characteristics of the rotorcraft; and reset the complementary filter in response to detecting the rotorcraft is grounded.
在实施方式中,旋翼飞行器包括:飞行控制计算机,其被配置成:从旋翼飞行器的第一飞行器传感器接收第一传感器信号;从旋翼飞行器的第二飞行器传感器接收第二传感器信号,第二飞行器传感器与第一飞行器传感器不同;使用互补滤波器对第一传感器信号和第二传感器信号进行组合以确定旋翼飞行器的估算垂直速度;根据旋翼飞行器的估算垂直速度而调节旋翼飞行器的飞行控制设备,从而改变旋翼飞行器的飞行特性;以及响应于检测到旋翼飞行器着地而重置互补滤波器。
