编码器的误差不仅与位置有关,还与速度、加速度等运动参数有关,分析编码器细分误差的产生原因,给出细分误差的计算公式,建立了匀变速运动中编码器光电信号的数学模型,通过计算机模拟仿真,提出了匀变速编码器光电信号参数特征的提取方法,即对实际采集的信号进行等间隔处理后,进行谐波分析,可以恢复出较真实的光电信号参数,进而计算出细分误差,最后给出了本方法的适用条件。 The error of the encoder is not only related to the position but also related to the motion parameters such as speed and acceleration. The reason why the encoder subdivision error is analyzed is given. The calculation formula of the subdivision error is given. And the mathematics of encoder photoelectric signal Model, through the computer simulation, the parameter extraction method of optical signal parameters of uniform variable speed encoder is put forward. That is to say, after the actual collected signals are processed at equal intervals, harmonic analysis can recover the more true parameters of the optical signals and then calculate The subdivision error, and finally gives the application of the conditions of the method.
