The application provides a control method, device and
system for improving cross-direction ride comfort of an
airplane, and belongs to the technical field of flight control. Three sets of lateral acceleration sensors are arranged on the longitudinal axis of the
airplane, and are respectively located at the front cabin
nose, the
airplane body
centroid and the rear cabin
tail, so as to obtain lateral overload signals of different positions of the airplane when the airplane is disturbed by
crosswind. In combination with three-axis
angular velocity signals of the airplane, the front cabin additional lateral overload and the rear cabin additional lateral overload are obtained after filtering
processing. Through
gain adjustment and amplitude limiting superposition, target
aileron differential instructions and target
rudder instructions are formed, the
aileron and the
rudder are deflected to generate lateral force and moment, the lateral force influence brought by the gust disturbance is offset, and the purpose of improving the passenger ride comfort is achieved. The application has simple
hardware structure, high
signal reliability and easy
engineering implementation, and can be used for improving the long-time cross-direction
ride quality of a large passenger airplane.
