Q-MEMS陀螺零偏补偿技术研究

Temperature compensation for Q-MEMS gyro

摘要: 在对某型Q-MEMS(石英音叉陀螺)进行大量高低温环境试验的基础上，根据试验数据，建立了一种基于陀螺工作时间的零偏温度补偿模型，并用该模型对新测的试验数据进行了预测补偿。补偿结果表明：Q-MEMS陀螺经该模型补偿后可以将零偏减小至少一个数量级，并进一步提高了零偏稳定性，有效补偿了陀螺上电后的启动漂移，完全满足工程上的实时补偿要求。因此，该模型具有很强的工程实用价值。

Abstract: Based on a lot of temperature experiments of Q-MEMS gyro, a novel temperature compensation model based on operation time is established according to the experiment data. The compensation prediction is performed to the new experimental data, and the results of compensations show that the bias is reduced to at least one tenth of the original. And the bias stability is also enhanced. The model can meet the requirement of realtime compensation and can be used in the application of Q-MEMS gyro.
