Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, a deeply redundant integrated three-redundancy electromechanical servo mechanism provided by the present invention includes a three-redundancy servo controller 1 , a three-redundancy actuator 2 , a load 3 and a three-redundancy potentiometer 4 .

[0014] Such as figure 1 As shown, the three-redundancy servo controller 1 includes a first controller 101 , a second controller 102 , a third controller 103 , a first driver 104 , a second driver 105 , and a third driver 106 . The first controller 101, the second controller 102, and the third controller 103 are connected in parallel. The control signal input terminal of the first controller 101 inputs the first angle swing control signal, and the output terminal of the first controller 101 communicates with the input terminal of the first driver 104 . The control ...

Abstract

The invention belongs to electromechanical servo mechanisms, and particularly discloses a high-redundancy integrated tri-redundancy electromechanical servo mechanism which comprises a tri-redundancy servo controller, a tri-redundancy actuator, a load and a tri-redundancy potentiometer, wherein the signal input end of the tri-redundancy servo controller is communicated with the input end of the tri-redundancy actuator; one output end of the tri-redundancy actuator is communicated with the input end of the load; the other output end of the tri-redundancy actuator is communicated with the input end of the tri-redundancy potentiometer; the feedback output end of the tri-redundancy potentiometer is communicated with the feedback input end of the tri-redundancy servo controller; being output to the tri-redundancy servo controller, the control signal is converted into a motor three-phase current signal through the tri-redundancy servo controller; a motor drives the tri-redundancy actuator to work; the tri-redundancy actuator drives the load to deflect; the tri-redundancy potentiometer acquires a load deflection signal, and feeds back the load deflection signal to the tri-redundancy servo controller. Through the adoption of the high-redundancy integrated tri-redundancy electromechanical servo mechanism, the maintenance performance and the reliability of a secondary servo mechanism of an aircraft can be obviously improved.

Description

technical field [0001] The invention belongs to an electromechanical servo mechanism, in particular to an electromechanical servo mechanism used for aircraft servo control. Background technique [0002] At present, the maintenance of the secondary servo mechanism of the existing aircraft is difficult, and the problem of oil leakage is relatively serious; the brushed DC motor used needs to be regularly blown off the toner, which is inconvenient to maintain and is prone to sparks when working under high vacuum This phenomenon also brings hidden dangers to product safety. Contents of the invention [0003] The purpose of the present invention is to provide a deeply redundant integrated three-redundancy electromechanical servo mechanism, which can significantly improve the maintenance performance and reliability of the aircraft's secondary servo mechanism. [0004] The technical solution for realizing the purpose of the present invention: a deeply redundant integrated three-r...
