Embodiment Construction

[0017] The first embodiment of the present invention provides an intelligent inlet guide vane control method based on the concept of distributed control, which is specifically implemented as follows: FADEC (full authority digital electronic controller) 1 sends control instructions (angle, digital signal) through the CAN bus, intelligent The control unit 2 receives instructions from the CAN bus, parses the digital control instructions into analog control signals and performs internal analysis and calculation of the control requirements, and then sends instructions to the electro-hydraulic servo valve 3, and the electro-hydraulic servo valve 3 follows the received control instructions Start to work, control the amount of oil entering the oil chamber of the actuator 4, thereby driving the actuator 4 to move, and the actuator 4 drives the guide vane 5 to move through a rigid connection; RVDT (angular displacement sensor) 6 detects the inlet guide vane 5 in real time The movement si...

Abstract

he invention provides a distributed-control-idea-based intelligent imported guide vane control method and apparatus. On the basis of an integrated design of an intelligent control unit and an electro-hydraulic servo valve, control delay is eliminated; the calculation task of an FADEC is reduced by controlling task issuing; because an angular displacement signal is communicated to the FADEC by a CAN bus, compared with an original analog signal type transmission way, the provided transmission way enables the total weight of the cable to be reduced due to reduction of the cable number from 6 to at least 2 and the electromagnetic interference caused by long-distance analog transmission to be avoided; and on the basis of the modularization and universal design, modularization part replacement can be realized when maintenance is needed. Therefore, the system control performance is improved and the system reliability and maintainability are enhanced. The method and apparatus meet the intelligent and modularized design idea of the distributed control system; and seamless joint with other units of the distributed control system can be realized by using the power bus and CAN bus interfaces.

Description

technical field [0001] The invention belongs to the technical field of intelligent actuator control of an aero-engine distributed control system, and relates to an intelligent inlet guide vane control method and device based on a distributed control concept. Background technique [0002] At present, the inlet guide vane control of aero-engine adopts centralized control, that is, the FADEC (Full Authority Digital Electronic Controller) is centrally placed in a specially designed chassis. The electrical signal of the RVDT (angular displacement sensor) is transmitted to the FADEC (full authority digital electronic controller) through the cable, and the FADEC calculates according to a certain control algorithm, and then transmits the electro-hydraulic control signal to the inlet guide vane control device through the cable. Signal processing, execution of control algorithms, communication, storage, and redundancy management are all completed by FADEC. There are deficiencies in t...
