Control method for a landing gear system, landing gear system and aircraft

Abstract

The application discloses a control method of a landing gear system, a landing gear system and an aircraft, and relates to the technical field of aerospace engineering. The control method comprises the following steps: setting a corresponding relationship between an input force and a pose of a wheel assembly under a standard working condition as a standard corresponding relationship between the input force and the pose; predicting an input force received by the wheel assembly at a next moment as a predicted input force; predicting a pose of the wheel assembly at the next moment according to the standard corresponding relationship based on the predicted input force as a predicted standard pose; predicting the pose of the wheel assembly at the next moment based on a current pose and a current pose change rate of the wheel assembly as a predicted actual pose; and controlling a plurality of motion branches in a mechanical neural network to adjust the pose of the wheel assembly according to the predicted standard pose and the predicted actual pose. The application can reduce the bumping of an aircraft during take-off and landing.
