摘要
本文根据影响编码器光电信号的因素,利用实测的Lissajous图及Matlab超强的数据处理功能,提出利用Matlab仿真评估编码器细分误差的方法。针对编码器莫尔条纹原始信号的正弦性、正交性、等幅性及含直流电平这几种典型特征,利用Matlab仿真对产生误差的原因进行单项分析评估。
A simulated evaluation method of interpolation errors in photoeletric encoder is described o The sampled signals provide Lissajous ,then the signals are processed to calculate the interpolation errors by Matlab. The sine,orthogonality,equal-amplitude and direct current voltage characteristics of encoder＇ s analog signals are each evaluated by simulating evaluation method using Matlab.
