Finite time observer for nonlinear systems

IFAC Proceedings Volumes, 2006
Abstract This paper proposes a nonlinear finite time convergent observer that does not require to compute any inverse coordinate transformation. The finite time estimate is recovered from two asymptotically convergent estimates which have linear error dynamics in transformed coordinates through the transformation Jacobian only.

Observer-Based Finite-Time Modified Projective Synchronization of Multiple Uncertain Chaotic Systems and Applications to Secure Communication Using DNA Encoding

IEEE Access, 2019
This paper studies an observer-based finite-time scheme for two modified projective synchronization modes, including the synchronization of multiple uncertain chaotic response systems to one drive system and transmission synchronization.

Finite-Time State Estimation for an Inverted Pendulum under Input-Multiplicative Uncertainty

Robotics, 2020
A sliding mode observer is presented, which is rigorously proven to achieve finite-time state estimation of a dual-parallel underactuated (i.e., single-input multi-output) cart inverted pendulum system in the presence of parametric uncertainty. A salient

Positiveness and Observer-Based Finite-Time Control for a Class of Markov Jump Systems with Some Complex Environment Parameters

Complexity, 2018
An observer-based finite-time L2-L∞ control law is devised for a class of positive Markov jump systems in a complex environment. The complex environment parameters include bounded uncertainties, unknown nonlinearities, and external disturbances.

Hybrid finite‐time fault‐tolerant consensus control of non‐linear fractional order multi‐agent systems based on fault detection and estimation

IET Control Theory & Applications
This paper addresses the problem of achieving finite‐time fault‐tolerant consensus control for a class of non‐linear fractional‐order multi‐agent systems (NFO‐MAS) using finite‐time fault detection and estimation, as well as a finite‐time state observer.

Robust finite-time stabilization and observation of a planar system revisited [PDF]

2015 54th IEEE Conference on Decision and Control (CDC), 2015
The second order planar nonlinear affine control problem is studied. A homogeneous robust finite-time stabilizing control is developed for the most general case of matched and, the more challenging, mismatched nonlinear perturbations. A homogeneous observer is designed for the planar system.
