چکیده

Abstract: In this paper, a continuous finite-time-convergent differentiator is presented based on a strong Lyapunov function. The continuous differentiator can reduce chattering phenomenon sufficiently than normal sliding mode differentiator, and the outputs of signal tracking and derivative estimation are all smooth. Frequency analysis is applied to compare the continuous differentiator with sliding mode differentiator. The beauties of the continuous finite-time-convergent differentiator include its simplicity, restraining noises sufficiently, and avoiding the chattering phenomenon.

Systematic Approach to Design a Finite Time Convergent Differentiator in Second Order Sliding Mode Controller

This paper presents a systematic approach to design a Lyapunov based super twisting differentiator. The differentiator will be shown convergent in a finite time whilst the relevant time is accurately estimated.  This differentiator is the main part to establish the sliding surface in higher order sliding mode. The differentiator  is used in the prescribed control structure  to regulate pressure...

Design and analysis of continuous hybrid differentiator

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 of derivative estimation by introducing a perturbation parameter, but also the dynamical performances are improved by adding linear correction terms to the nonlinear ones. Moreover, strong robustness ability is obtai...

Robust exact uniformly convergent arbitrary order differentiator

An arbitrary order differentiator that, in the absence of noise, converges to the true derivatives of the signal after a finite time independent of the initial differentiator error is presented. The only assumption on a signal to be differentiated (n−1)-times is that its n-th derivative is uniformly bounded by a known constant. The proposed differentiator switches from a newly designed uniform ...

Design and Simulation of VFA and CFA Based Integrator and Differentiator using NI Multisim and their Comparison

VFA is used for most of the analog circuit design but in many high frequency applications like integrator and differentiator it’s finite slew rate, finite gain bandwidth product limitation degrades its performance. Thus, the introduction of CFA possessing a number of advantages including high slew rate due to its current feedback architecture, closed loop bandwidth that is independent of closed...

Design of first-order differentiator utilising FIR and IIR sub-filters

In this paper, we propose a novel approach for constructing the first-order differentiator. It has been shown recently that an efficient Finite Impulse Response (FIR) wideband differentiator can be synthesised when applying the multirate and Frequency-Response Masking (FRM) techniques. The overall signal processing task is shared between a very loworder differentiator and an FIR half-band filte...
