Problems solved by technology

However, due to the complex and changeable state of the aircraft landing runway, the friction characteristics of different runway surfaces are quite different, so this kind of control method lacks the adaptability to the change of the runway surface state.

Abstract

The invention provides a two-wheel control method based on an adaptive runway. By measuring whether the aircraft slips, the depth of the wheel slippage on both sides is judged. If the difference between the wheel speed and the predetermined reference speed is less than the deep slip threshold, it is shallow slip, shallow slip control, independent control between the wheels. The scheme of the present invention, aiming at the problem that the traditional braking control method lacks adaptability to the change of the surface state of the runway, proposes the synchronous processing logic of the wheel skidding, which enhances the adaptability of the braking system to the changing runway, strengthens the synchronous skidding, and improves the braking process of the aircraft. security.

Description

technical field [0001] The invention relates to the field of aircraft navigation, in particular to an adaptive runway-based two-wheel control method, device and memory. Background technique [0002] The aircraft braking system is a subsystem with relatively independent functions on the aircraft, and its function is to absorb the kinetic energy of the aircraft when it lands. Aircraft Antiskid Brake System (ABS) is based on the traditional braking system and adopts a certain control method to realize the automatic adjustment of the braking torque, so as to prevent the locking of the aircraft wheel caused by excessive braking pressure during braking. The current main anti-skid braking control strategy has better anti-skid braking effect on a single runway surface condition. However, due to the complex and changeable state of the aircraft landing runway, the friction characteristics of different runway surfaces are quite different, so this kind of control method lacks the adapt...
