Journal ArticleDOI
Finite-time and fixed-time stabilization
TL;DR: New nonlinear control laws are designed for robust stabilization of a chain of integrators using Implicit Lyapunov Functions for finite-time and fixed-time stability analysis of nonlinear systems.
Journal ArticleDOI
Interval State Estimation for a Class of Nonlinear Systems
TL;DR: The goal of this technical note is to design interval observers for a class of nonlinear continuous-time systems and shows that it is usually possible to design an interval observer for linear systems by means of linear time-invariant changes of coordinates even if the system is not cooperative.
Journal ArticleDOI
Interval state observer for nonlinear time varying systems
TL;DR: It is shown that under some mild conditions the cooperativity of an LTV system can be ensured by a static linear transformation of coordinates and the efficiency of the proposed approach is demonstrated through numerical simulations.
Journal ArticleDOI
Control of Nonlinear and LPV Systems: Interval Observer-Based Framework
TL;DR: An application of the proposed technique shows that a robust stabilization can be performed for linear time-varying and linear-parameter-variesing (LPV) systems without assumption that the vector of scheduling parameters is available for measurements.
Journal ArticleDOI
Interval estimation for LPV systems applying high order sliding mode techniques
TL;DR: The problem of design of interval observers for Linear Parameter-Varying (LPV) systems, containing non-detectable or non-strongly-observable parts, is addressed and it is shown that HOSM techniques allows us to relax the applicability conditions of standard interval observer design methods.
