Multivalued finite-time observers for a class of nonlinear systems
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017We consider a class of nonlinear systems which are not observable, and can have a finite number of indistinguishable trajectories. In general, this implies that a single-valued observer does not exist. In this paper we propose the construction of a multivalued observer, which is able to estimate the full set of indistinguishable trajectories. Moreover,

Finite-time observer for nonlinear dynamic systems
1973 IEEE Conference on Decision and Control including the 12th Symposium on Adaptive Processes, 1973This paper introduces finite-time observers for a class of non-linear dynamic systems. The concept of observability is first shown to be a necessary condition for the existence of a finite-time observer for the system. Then a finite-time observer for an important class of systems is constructed with a novel structure which avoids the use of ...

An Adaptive Finite Time Sliding Mode Observer [PDF]
, 2017 This chapter develops a novel adaptive ?nite time observer which can achieve ?nite time unmatched parameter estimation and ?nite time system state observation. The proposed approach has strong robustness and rapid convergence. A step by step proof is given which employs ?nite time stability and sliding mode principles.

Global finite-time observers for a class of nonlinear systems
Kybernetika, 2013Summary: Global finite-time observers are designed for a class of nonlinear systems with bounded varying rational powers imposed on the increments of the nonlinearities whose solutions exist and are unique for all positive time. The global finite-time observers designed in this paper have two homogeneous terms. The global finite-time convergence of the

An explicit finite difference method for finite‐time observers
International Journal of Robust and Nonlinear Control, 1994AbstractIn this paper we present a numerical method for estimating the current state of a nonlinear control system. We use finite differences to discretize a modified version of the finite‐time observer equations in James. The discretized equations are simple and easily programmed.

On the Observability of Polynomial Systems, I: Finite-Time Problems
SIAM Journal on Control and Optimization, 1979Different notions of observability are compared for systems defined by polynomial difference equations. The main result states that, for systems having the standard property of (multiple-experiment initial-state) observability, the response to a generic input sequence is sufficient for final-state determination.

Finite Time Observer Design for Teleoperation System
2019The finite-time output feedback synchronization control problem is considered for a bilateral teleoperation system in the presence of the modeling error and disturbance. A new observer is designed for the velocity estimation by using neural network approximation and fast terminal sliding mode method. It is shown that the resulting velocity error system
