Abstract

Abstract

VHDL is the best hardware description language in the field of system design.Based-on the features of photoelectric encoder signal used in feedback measurement of position and velocity, the method by which the circuits of frequency-multiplier and phasedemodulation is designed in the FPGA by VHDL was introduced in this paper. It has improved resolving power of coder and realized signal detection and position servo control of high accurate and high stable.
