Electric inertia navigation turntable galloping state determination device and method thereof

Abstract

The invention relates to an electric inertia navigation turntable galloping state determination device and a method thereof. An electric inertia navigation turntable comprises a rotating shaft for driving rotation of the turntable and a fixed frame shaft which sleeves the outer circumference of the rotating shaft. The device is characterized in that a magnetic piece mounting seat is mounted on theshaft end of the rotating shaft; an inductive magnetic piece is attached to the magnetic piece mounting seat; two sensors are mounted on the end surface of the frame shaft; two sensors are symmetrically arranged at the center of the frame shaft; when rotating one turn with the rotating shaft, the inductive magnet piece passes through two sensors in sequence and can trigger the sensors to generatecorresponding sensing signals; and two sensors send the generated corresponding sensing signals to a signal processing unit for determining the galloping state of the electric inertia navigation turntable. The device has the advantages of simple structure and convenient disassembly and maintenance. The determination method using the device utilizes a fixed angle time measuring method to determinethe rotational speed. The method is convenient, quick, reliable, and easy to be engineered.

Description

technical field [0001] The invention relates to the technical field of numerical control inertial navigation testing equipment, in particular to a judging device and method for the flying state of an electric inertial navigation turntable. Background technique [0002] The electric inertial navigation turntable can provide accurate angular position, angular velocity and angular acceleration test benchmarks. It is an electric closed-loop control device. Due to the characteristics of the closed-loop motion control system, when it is subject to uncertainties such as load characteristics, control algorithms and component failures When the influence of factors, there will inevitably be serious failures of out-of-control speeding. Common causes of turntable speeding are as follows: loss of feedback signal, saturation of servo output, breakdown of power amplifier tube, etc. The turntable motor will reach or exceed the no-load speed of the motor during flying, which is far greater ...
