Abstract

The invention discloses a method and a system for recovering vibration faults of an electric steering engine. According to the method, a diagnosis result is firstly output; when the diagnosis result is a fault code, the fault code is analyzed and treated and a recovery enabling signal of the vibration faults is output; parameters of a control circuit are modified so as to recover the vibration faults. According to the scheme, the automatic recovery of the vibration faults of the electric steering engine is realized; when the electric steering engine breaks down, the fault is responded in time and the automatic recovery is carried out; the maintainability of the system is provided and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the field of electric steering gear, in particular to a method and system for recovering from an oscillation fault of an electric steering gear. Background technique [0002] The electric steering gear is the executive mechanism of the electric steering system, which is widely used in the rudder surface control of the aircraft. The electric steering gear is composed of a motor, a reducer mechanism, and a position feedback potentiometer. [0003] At present, during the operation of the electric rudder system, when the electric rudder fails, maintenance personnel need to analyze and deal with the failure of the electric rudder, and perform manual maintenance. In this way, detection and manual maintenance will inevitably take a long time , so that the rapid response capability of the system is reduced. [0004] However, with the development of weapon systems, it has become a development trend for the electric rudder system to hav...
