本文介绍了一种新的变量 M/T 方法，称为跳跃变量 M/T 方法，用于电机伺服系统中光学增量编码器的速度测量。该方法与传统的可变M/T方法一样，以可变间隔对编码器脉冲和高频时钟脉冲进行计数，从而确保了高速和低速下的高测量精度。另外，通过计数周期的跳跃触发时间，可以减少至少一个采样周期的速度延迟，保证了更准确的速度反馈信号和电机系统的快速响应。
In this paper, a new variable M/T method called leap variable M/T method is introduced for speed measurements by optical incremental encoders in motor servo systems. In this method, both encoder pulse and high frequency clock pulse are counted in a variable interval as conventional variable M/T method which ensures the high measurement accuracy in both high speed and low speed. Furthermore by leap trigger time of counting period, the speed delay can be reduced by at least one sampling period, which guarantees a more accurate speed feedback signal and rapid response of motor system.
