Problems solved by technology

The lower Larmor precession attenuation frequency results in that after a fixed angular velocity input, the output of the angular velocity signal must take a long time (>5s) to converge before reaching the steady-state value, which makes this type of gyroscope work well under complex or high-frequency rotational input. It is difficult for the output signal to reach a steady state, and the dynamic range of the measured angular velocity input is greatly limited

Abstract

A method for increasing the response speed of an SERF atomic spin gyroscope based on transient response calculation comprises the following steps: calibrating system parameters by using the magnetic field response of the SERF atomic spin gyroscope, constructing a state space matrix of the SERF atomic spin gyroscope by using the system parameters, collecting output signals when the SERF atomic spin gyroscope works, and calculating the electron transverse polarizability. According to the method, the electron transverse polarizability is utilized to calculate the nucleon transverse polarizability, transient electron and nucleon transverse polarizability information is utilized to construct a state vector, and angular velocity input is calculated, so that the response speed of the SERF atomic spin gyroscope under rotation input can be greatly improved, the problem of double-axis coupling is solved, and the applicable range of the atomic gyroscope is expanded.
