摘　　要：光电脉冲编码器输出脉冲信号到达滤波器的信号为合法信号与干扰信号的叠加,为了滤除干扰信号和得到合法信号,有基于合法信号认知并滤出合法信号以外的各种信号和基于干扰信号认知并滤出干扰信号两种滤波策略。由于脉冲信号的特征容易被认知,故对脉冲信号的滤波宜采用基于合法信号认知的滤波策略。本文以一实际永磁同步电动机的旋转脉冲编码器为例详细介绍了这种策略及其实现,并采用FPGA构成了滤波器进行实验研究。实验结果表明了方法的正确性。The output pulse signal of photoelectric pulse encoder gets to the wave filter signal is stacked by legal signal and disturbing signal.In order to filter disturbance signal and get the legal signal , owing to legal signal cognize filtering disturbance and cognize disturbance and filtering two species wave filtering tactics are provided.Because of easy pulse signal characteristic cognition,legal signal cognition-based wave filtering method is adopted.One actual permanent synchronous motor winding machine rot...
