A fiber optic gyroscope temperature compensation method, device, electronic equipment and storage medium

Abstract

The invention discloses a fiber optic gyroscope temperature compensation method, device, electronic equipment and storage medium. The method includes: lowering the fiber optic gyroscope to a first preset temperature at a preset rate of change at a preset conventional temperature, and then heating up to a second preset temperature at a preset rate of change, and recording the temperature of the fiber optic gyroscope Each temperature data in the change process and each gyro angular rate data corresponding to each said temperature data; determine the temperature transition time according to the gyro angular rate data; build a gyro zero bias temperature compensation model based on the temperature transition time, through the The gyroscope zero bias temperature compensation model performs temperature compensation on the optical fiber gyroscope to be compensated. The invention realizes the consideration of the influence of the previous temperature of the gyroscope, and constructs a temperature compensation model through the temperature interval difference of several temperature intervals on the time axis, which can effectively compensate the temperature drift of the gyroscope.

Description

technical field [0001] The present application relates to the technical field of inertial positioning and orientation, and in particular, relates to a fiber optic gyroscope temperature compensation method, device, electronic equipment and storage medium. Background technique [0002] The fiber optic gyroscope is an angular rate sensor based on the Sagnac effect. Due to its low cost, simple process, high reliability, and strong shock and vibration resistance, its application prospects have attracted much attention and it has become one of the mainstream sensors. However, the main components that make up the fiber optic gyroscope, such as fiber optic rings and light sources, are more sensitive to temperature, which causes the output of the fiber optic gyroscope to be greatly affected by temperature, and the gyroscope output drifts greatly with temperature changes, which reduces the measurement accuracy of the fiber optic gyroscope. Therefore, temperature drift compensation for...

Problems solved by technology

The neural network model has great advantages in terms of accuracy, but its algorithm is complex, which is not conducive to engineering implementation

Most of the existing polynomial models only consider the influence of the current temperature of the gyroscope, but the temperature drift of the fiber optic gyroscope is not only related to the current temperature, but also has a greater relationship with the previous temperature of the gyroscope, and the closer the forward temperature is to the current temperature. The greater the influence of gyro temperature drift
