A study on precision position measurement method for analog quadrature encoder

This paper presents new interpolation algorithm for measuring high resolution position information which is propered to nano servo control motor using analog quadrature encoder. In the past, there is a large memory and two high price A/D converter for high resolution analog quadrature encoder interpolation. but this paper show that it can make high resolution interpolate using small memory, one A/D converter and comparator. Experimental results show that the proposed algorithm for high resolution position is useful.
