Abstract

Optical incremental encoders are widely used for the speed measurements in motor servo systems due to low cost and high performance. But it is difficult to use the encoders when wide speed range, high accuracy and extremely short responding time are required at the same time in high performance servo systems. In this paper, an improved variable M/T method is introduced. In this method, both encoder pulse and high frequency clock pulse are counted in a variable interval which ensures the high measurement accuracy in both high speed and low speed. By speed estimation algorithm, the rapid response can be obtained even at very low speed.
