Implementation of Fixed Sampling Period M/T Method Based on VHDL
Abstract:
Take insufficiency of classical velocity measurement methods into consideration, this paper introduces a method which has a good test accuracy in a wide range, fixed sampling period M/T method, to determine velocity and position information of the encoder. Firstly, its measurement principle is analyzed in detail through logic and timing relationship. Then realization of every module is achieved with VHDL. Finally, ModelSim is used to simulation and test to verify the correctness of the method. In the future, it can be widely used in practical applications.
