Double-input selective execution control method for fly-by-wire aircraft

Abstract

The invention relates to a telex plane double-input selective execution control method, which comprises the steps of 1) determining a stalling angle of attack; 2) inputting side slope data and judging whether the input side slope data exceeds 33 degrees or not; 3) judging whether a GPWS (Ground Proximity Warning System) alarm is triggered or not; 4) calculating a permission coefficient delta; 5) judging whether double-input control terminal commands exist or not; 6) in a large angle of attack judgment mode, a ground proximity mode and a glide slope approach mode, performing calculation to obtain a control angle alpha for pitching operation and inputting the control angle alpha into an elevator control computer; in a high-side-slope mode, performing calculation to obtain a control angle alpha for rolling operation and inputting the control angle alpha into an aileron spoiler control computer; 7) performing selective execution control to a plane. The telex plane double-input selective execution control method provided by the invention can cope with the situation of double control input due to a reason that telex plane double pilots input different control commands.

Description

technical field [0001] The invention belongs to the technical field of avionics control systems, and relates to a telex control method for a two-person crew system, in particular to a dual-input selective telex aircraft applied to the bilateral control input terminals of large commercial airliners in my country without physical action connection Execute the control method. Background technique [0002] Fly-By-Wire (FBW) is a method in the aviation field that converts the control input of the aircraft pilot into an electrical signal through a converter, processes it through a computer or an electronic controller, and then transmits it to the actuator through a cable. A steering system that eliminates the mechanical transmission and hydraulic lines in traditional steering systems. [0003] The existing fly-by-wire flight control method generally adopts the following three methods to deal with two pilots inputting different controls at the same time: [0004] 1. Vector sum add...

AI Technical Summary

Problems solved by technology

[0006] 1. Blind addition has no directivity and pertinence; 2. Increase the weight of structural redundancy; 3. It is difficult to meet the needs of flight attitude intervention under special circumstances (such as the double input situation in the AF447 air crash, where the two pilots different judgments)
