A reduced-order observer for velocity estimation of N-link manipulators
(Acta Press, 2000-01)
An exponentially nonlinear reduced-order observer for robot manipulators is developed. Velocity estimation of N-link manipulators is performed by integrating only N differential equations. Consequently, computational effort ...
An LMI Approach to Full- and Reduced-Order Switched Luenberger Observers for Switched Affine Systems
(2016-12-01)
This work deals with reduced-order Luenberger-like observer design and control for switched affine systems. Formulation of state-dependent and dynamic output-dependent switching laws for those systems was already addressed, ...
Sequences Detection of an Unbalanced Sinusoidal Voltage of Unknown Frequency Using a Reduced-Order Observer
(Institute Of Electrical And Electronics Engineers, 2013-07)
This paper presents a globally convergent nonlinear observer capable of recovering the positive and negative sequences of an unbalanced grid voltage. The proposed algorithm has frequency adaptation, and is therefore, in ...
Design of reduced-order nonlinear observers for energy conversion applications
(Institution of Engineering and Technology, 2010-05)
Here a systematic technique to design a reduced-order nonlinear observer for estimating signals in application to energy conversion systems is introduced. This observer presents a linear error dynamics in estimated variables ...
Estudo de um sistema de controle sensorless para máquinas síncronas de ímãs permanentes internos
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-03-06)
This paper presents a study of state observers for the control of permanent magnet synchronous electric machines. In order to ensure the correct functioning of the machine, control techniques employed in PMSMs require ...
Discrete-time reduced order neural observers
(2009)
A nonlinear discrete-time reduced order neural observer for the state estimation of a discrete-time unknown nonlinear system, in presence of external and internal uncertainties is presented. The observer is based on a ...
Discrete-time reduced order neural observers
(2009)
A nonlinear discrete-time reduced order neural observer for the state estimation of a discrete-time unknown nonlinear system, in presence of external and internal uncertainties is presented. The observer is based on a ...
Discrete-time reduced order neural observers for uncertain nonlinear systems
(2010)
This paper focusses on a novel discrete-time reduced order neural observer for nonlinear systems, which model is assumed to be unknown. This neural observer is robust in presence of external and internal uncertainties. The ...
Specific growth rate estimation in (fed-)batch bioreactors using second-order sliding observers
(Elsevier, 2011-08)
This paper addresses the estimation of specific growth rate of microorganisms in bioreactors using sliding observers. In particular, a second-order sliding observer based on biomass concentration measurement is proposed. ...
