基于双尺度的单轴陀螺高精度转速测量技术研究

单自由度的陀螺能够提供给载体较高精度的转动速率信息，其自身的检测和标校要求非常高，需要在很大的速率范围内进行高精度的测量。但是目前常用的转速测量方法局限性较大，无法满足陀螺高精度、大范围的要求，因此，文章设计了双尺度测速方法，测量误差可以根据实际进行控制。而且为稳定信号，引入了锁相环技术提升了系统抗干扰的能力，并利用单片机技术实现了高精度转速测量。这种转速测量方法具有测量准确度高、测量范围宽和测量精度与被测转速无关等优点，具有广阔的应用前景。

Research on high precision rotation rate measurement of single-axis gyroscope based on double scale

Despite the single-axis gyro can provided the precision information about rotation,there have many very rigorous demands for its measurement and calibration,which need high precision measurement to large speed field.But there has few ways to satisfy these demands,so the paper designes a method to measure the rotation rate that the error can be control based on practical request,and introduced the PLL to stabilize the signal.Finally,it uses the microcomputer to utilize the method.The measurement system is of...
