Design and analysis of continuous hybrid differentiator
Xinhua Wang, Hai Lin
In this paper, a continuous hybrid differentiator is presented based on a strong Lyapunov function. The differentiator design can not only reduce sufficiently chattering phenomenon…
Design and frequency analysis of continuous finite-time-convergent differentiator
Xinhua Wang, Hai Lin
In this paper, a continuous finite-time-convergent differentiator is presented based on a strong Lyapunov function. The continuous differentiator can reduce chattering phenomenon s…
Two-step differentiator for delayed signal
Xinhua Wang, Hai Lin
This paper presents a high-order differentiator for delayed measurement signal. The proposed differentiator not only can correct the delay in signal, but aslo can estimate the unde…
Universal approximation using differentiators and application to feedback control
Xinhua Wang
In this paper, we consider the problems of approximating uncertainties and feedback control for a class of nonlinear systems without full-known states, and two approximation method…
High-order integral-chain differentiator and application to acceleration feedback
Xinhua Wang
The equivalence between integral-chain differentiator and usual high-gain differentiator is given under suitable coordinate transformation. Integral-chain differentiator can restra…
Frequency characteristics based on describing function method for differentiators
Xinhua Wang
In this paper, describing function method is used to analyze the characteristics and parameters selection of differentiators. Nonlinear differentiator is an effective compensation…
Rapid-convergent nonlinear differentiator
Xinhua Wang, Bijan Shirinzadeh
A nonlinear differentiator being fit for rapid convergence is presented, which is based on singular perturbation technique. The differentiator design can not only sufficiently redu…
