Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0033] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0034] In order to achieve stable control of the aircraft after the common mode failure of the actuator control electronics (ACE), the auxiliary flight control unit (AFCU) is designed to output actuator position commands to a specific remote electronic con...

Abstract

The invention discloses a servo control electronic system and an REU instruction conversion method thereof. The system comprises a plurality of first-type remote electric control units REUs, a plurality of second-type REUs, an actuator control electronic ACE and an auxiliary flight control unit AFCU. Each first-type REU is connected to one ACE, and each second-type REU is connected to one ACE andone AFCU; the ACE is used for sending a servo control instruction to the first-type REU or the second-type REU connected with the ACE; the AFCU is used for sending the servo control instruction to thesecond-type REU connected with the AFCU; and the REU is connected with one actuator and is used for controlling the movement of the corresponding actuator through a servo control instruction sent bythe ACE or the AFCU. According to the embodiment of the invention, the risk that an aircraft is out of control thoroughly due to the fact that all REUs lose control instructions because ACE hardware has a common-mode fault in a civil aircraft fly-by-wire flight control system with an existing architecture is solved.

Description

technical field [0001] The invention relates to but not limited to the technical field of flight control, in particular to a servo control electronic system and a REU command conversion method thereof. Background technique [0002] A fly-by-wire flight control system of a civil aircraft adopts the main flight control module (FCM) to provide the control calculation of the complete functions of the main flight control system, and the actuator control electronics (ACE) outputs the position commands of each actuator to each remote electronic control unit (REU), and then the servo closed-loop control circuit inside the REU realizes the structure of the position control of the actuator. [0003] The above architecture has the risk of common mode failure of several ACE hardware with the same design, causing all REUs to lose control commands, and thus the aircraft is completely out of control. Contents of the invention [0004] The purpose of the present invention: to propose a s...
