Abstract

During the vibration process, the output of the gyroscope will add a non-zero offset small amount based on the Earth's rotational speed component, which is the output error term of the gyroscope vibration. When the gyroscope adopts two different closed-loop models, the error magnitude of the same gyroscope is different. Therefore, selecting an optimal closed-loop model while adjusting appropriate closed-loop parameters is crucial for solving the vibration problem of gyroscopes. Firstly, compare the differences and stability conditions between the two closed-loop models; Secondly, analyze the reasons for the error terms generated during the vibration process of the gyroscope and the reasons for the different sizes of error terms generated by different models; Then simulate and analyze the output of gyroscope vibration under different closed-loop models. The simulation and specific experimental results indicate that selecting an optimal closed-loop model shortens the closed-loop integration delay time of the model, and maximizes the closed-loop gain as much as possible while ensuring that there are no resonance peaks in the closed-loop amplitude frequency characteristic curve. This can reduce the output error term of the gyroscope and improve its dynamic performance.
