Abstract


Pseudorandom position encoders enable an absolute position measurement using one code track based on a pseudorandom binary sequence (PRBS). Both serial and parallel pseudorandom code reading methods can be applied in these encoders. A reliable solution of an absolute position encoder that uses two mutually shifted pseudorandom code tracks is presented. The proposed solution is easier for practical realization, and has better performances regarding redundancy and reliability. The practical realization of this code reading method is also shown.
