SYSTEM AND METHOD FOR ROTORCRAFT ACTIVE LATERAL SHUFFLE FILTER

The invention relates to a system and method for a rotorcraft active lateral shuffle filter. In accordance with an embodiment of the present invention, a method of operating a rotorcraft includes receiving a measured yaw rate from a yaw rate sensor or a measured lateral acceleration from a lateral acceleration sensor of the rotorcraft, filtering the measured yaw rate or the measured lateral acceleration using a filter to form a filtered measured yaw rate or a filtered measured lateral acceleration, and regulating a yaw rate or a lateral acceleration of the rotorcraft based on the measured yawrate or the measured lateral acceleration. The filter includes a bandpass characteristic or a notch characteristic, and the filtering is configured to reduce lateral vibrations caused by airflow in atail section of the rotorcraft. 本发明涉及用于旋翼飞行器有源横向摆动滤波器的系统和方法。根据本发明的实施方式，种操作旋翼飞行器的方法包括：接收来自偏航速率传感器的测量偏航速率或来自旋翼飞行器的横向加速度传感器的测量横向加速度；使用滤波器对测量偏航速率或测量横向加速度进行滤波，以形成经滤波的测量偏航速率或经滤波的测量横向加速度；以及基于测量偏航速率或测量横向加速度来调节旋翼飞行器的偏航速率或横向加速度。滤波器包括带通特
