By virtue of the filtered signalsand their differentiated signals,tracking differentiator(TD) can be used to filtering a signal with random noise.Compare with traditional Kalman filter,TD filter has great research value in its practicality and simplicity of design.This paper focuses on hardware implementation and simulation of TD filter ,introduces mathematical model of TD in discrete time systems and simulated in MATLAB,then realized on the digital signal processor (DSP) F28379D.Fanally gives out the experimental results of TD filter's effects on MATLAB and hardware.The experimental results demonstrate that TD filter has great effectiveness in random noise filtering.
