A comparison study of advanced tracking differentiator design techniques
This paper presents a comparison study of four advanced tracking differentiators,including global robust exact differentiator,hybrid continuous nonlinear differentiator,robust exact uniformly convergent arbitrary order differentiator and Taylor expansion series based differentiator.The numerical simulations are performed by three typical signals with different type of noise to illustrate the performance of tracking differentiation,sensibility to noise and robustness ability.The results show that,over all,these differentiators could track derivate signal of low frequency signal well and Taylor expansion series based differentiator is more sensitive to noise than other three differentiators.
