Abstract

The invention relates to a fully automatic magnetic compensation method for a SERF atomic spin gyroscope based on a PID algorithm. This method performs three-axis magnetic compensation in a fully automatic sequence. First, a square wave scanning signal is loaded on the scanning axis coil, and the steady-state values ​​of the two gyroscope output signals caused by the high and low levels of the scanning axis coil square wave are collected and filtered. Finally, the difference between the two steady-state values ​​is made, and the PID algorithm is applied to the difference, and the PID parameters are automatically assigned according to the difference, and the difference at this moment and the difference at the previous moment are substituted into the PID algorithm to calculate a step voltage. And load the step amount to the compensation axis, repeat the above steps until the steady-state difference of the gyro output approaches zero and enters the error zone, then the magnetic field of the compensation axis coil reaches the compensation point, the single-axis compensation ends, and the next axis compensation starts. This method is automatically executed by the algorithm for three-axis magnetic field compensation, and each axis can be compensated to the zero magnetic compensation point. Compared with manual magnetic compensation, the speed is faster, the accuracy is better than 0.1nT, the operation is simple, and the volume is smaller.

Description

technical field [0001] The invention relates to an automatic magnetic compensation method for a SERF (Spin-Exchange-Relaxation-Free) atomic spin gyroscope based on a PID algorithm, which is applied to the field of active magnetic compensation of a SERF atomic spin gyroscope, and can rapidly Compensating the magnetic field of the SERF atomic spin gyroscope to the zero magnetic state provides the necessary conditions for the normal operation of the SERF atomic spin gyroscope. Background technique [0002] Aviation, aerospace, autopilot and other fields have an urgent need for high-precision inertial navigation, and the gyroscope is the core component of the inertial navigation system. The performance of the gyroscope directly determines the overall performance of the inertial navigation system. Atomic gyroscopes are considered to be an important development direction of a new generation of ultra-high-precision gyroscopes, and SERF atomic spin gyroscopes have been verified to h...
