| 摘 要： | 介绍了温度对硅微陀螺仪的零偏的影响机理，通过温度实验得知零偏随温度变化成复杂的非线性关系，并用最小二乘法拟合出了零偏在～40℃～80℃随温度变化的数学表达式；以FPGA芯片为主要器件设计了零偏温度补偿系统，并进行了温度实验测试，测试结果表明补偿效果明显。

| Abstract: | This paper introduces the influence of temperature variation on the bias of silicon micro-machined gyro- scope first, then derive the nonlinear relation between the bias and the temperature through temperature experiments and figure out the math expressions of the relations between bias and temperature from - 40~C to 80~C adopting least square method in terms of the data from above experiments. Finally, we design a temperature compensation system using a chip of FPGA and do some temperature experiment tests. The results of the tests show that the compensation effect is obvious. |
