Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay
In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...
متن کاملExact state estimation for linear systems with unknown inputs based on hierarchical super-twisting algorithm
A robust hierarchical observer is designed for linear time invariant systems with unknown bounded inputs under conditions of strong observability, providing exact state estimation. The main condition for designing the state estimator is the, so-called, strong observability condition. The supertwisting (secondorder sliding mode) algorithm is used in each step of the hierarchy; the continuity of ...
متن کاملEfficient super resolution time delay estimation techniques
In this paper, an e cient Weighted Fourier transform and RELAXation based algorithm (referred to as WRELAX) is rst proposed for the well-known time delay estimation problem. WRELAX involves only a sequence of weighted Fourier transforms. Its resolution is much higher than that of the conventional matched lter approach. One disadvantage associated with WRELAX is that it converges slowly when the...
متن کاملA Robust Adaptive Observer-Based Time Varying Fault Estimation
This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...
متن کاملTime Delay Estimation for Speech Signal Based on FOC-Spectrum
Higher-order statistics can be used for time delay estimation (TDE) to suppress spatially correlated Gaussian noise, since the higher-order cumulant of Gaussian signal is always zero. However, third-order statistics is invalid for those signals with zero skewness, speech signal as a typical one. In this paper, the fourth-order cumulant (FOC) spectrum is derived, based on which a TDE algorithm t...
