Abstract

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.
