陀螺仪角速度的检测与处理
摘要
对陀螺仪测量自动导航小车的角速度进行了理论分析
并对其角速度的采集作出了说明。针对陀螺仪采集自动导航小车瞬时角速度值时噪声信号往往淹没真实的角速度
对提取自动导航小车的真实角速度提出了几种方案
并通过实验证明其可行性。对小车角速度为45°/s时做了2种滤波
实验证明:2种算法有效地滤去噪声信号
大大降低了淹没角速度的范围。
Abstract
Analyzing the automated guided vehicle(AGV) angular velocity measured by gyroscope for the theroy and detailing to the angular velocity sampling.When the instantaneous angular speed value of the AGV is gathered by the gyroscope
the noise signal often floods the true speed.Several kinds of schemes in drawing the true angular speed of the AGV are proposed.Experiment shows its feasibility is proved.Two kinds filtration of AGV when it’s angular velocity is 45°/s is made.The experiment shows the two filtration algorithms filtered the noise signal effectively
and reduced the range of the flooded angular velocity greatly.
