On realization of signal processing based on tracking-differentiator for maglev train

The tracking-differentiator algorithm is adopted in the position and speed detection system and suspension system of maglev train to solve the practical problems of signal processing. The realization of signal processing based on tracking-differentiator in Field Programmable Gate Array (FPGA) is studied. In this paper, the tracking-differentiator algorithm is described with Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) and the calculation process is introduced. Meanwhile, the tracking-differentiator algorithm is simulated in MATLAB-Modelsim, and tested in the experiment. The simulation and experiment results illust rate that it is feasible to achieve the signal processing based on tracking-differentiator in FPGA.
