系列运动参数数字检测技术的研究

针对角度、角速度、线速度、位移等运动参数高精度检测的需求,研究检测精度高、范围宽、使用寿命长的系列运动参数数字式传感技术十分必要,而角速度的检测是其它参数检测的基础。采用增量式光电编码器和系列传感机构的全新设计以及基于角速度预估的变采样周期的M法测速方案,实现不同速度区间角速度的精确检测。结果表明角速度在15-1 500 r/min区间保持了相同的分辨率和精度。

Research on Digital Sensors for Kinematical Parameters Measurement

To meet the increasing requirement of high-precision measurement of kinematical parameters,such as angle,angular velocity,linear velocity,and displacement,it is very necessary to develop the digital sensor with high-precision,wide measurement range and long service life.The measurement of angular velocity is the foundation for other parameters' detection.The new design with incremental encoder and some sensing devices works out a solution.It adopts M method based on angular velocity prediction and variable ...
