Some new standpoints in the design of asymptotic functional linear observers
ESAIM: Proceedings and Surveys, 2015 The owl of Minerva spreads its wing only with the falling of the dusk. The aim of this work is to provide some new trends in the observation for linear systems. In the general framework of designing linear functional observers for

Functional Observability and the Design of Minimum Order Linear Functional Observers [PDF]
IEEE Transactions on Automatic Control, 2010 The design of a minimum-order linear functional observer for linear time-invariant systems has been an open problem for over four decades. This technical note provides a solution to this problem. The technical note also introduces the concept of Functional Observability/Detectability and shows that the well-known concept of Observability/Detectability ...

Flux linkage estimation strategies for sensorless field-oriented control of doubly-fed induction motor drive [PDF]
E3S Web of Conferences, 2021 In this paper authours propose two different strategies of flux linkage estimation for sensorless FOC system of doubly-fed induction motor drive implementation. Possibility to measure currents and voltages of rotor and stator circuits in doubly-fed motor

PLoS ONE, 2022 Human smooth pursuit eye movements and motion perception behave similarly when observers track and judge the motion of simple objects, such as dots. But moving objects in our natural environment are complex and contain internal motion. We ask how pursuit

Functional Observers for Descriptor Systems With Unknown Inputs
IEEE Access, 2023 This paper addresses the problem of estimating a functional vector for a class of linear time-invariant descriptor systems with unknown inputs. The unknown inputs are considered in both the system dynamics and measurement equations. The proposed observer

A Note on Functional Observability [PDF]
IEEE Transactions on Automatic Control, 2016 In this note, we propose an alternative to characterize the functional observability for linear systems. The main feature is that we obtain a necessary and sufficient condition for the existence of a stable multi-functional observer of a time-invariant linear system.

Brain-to-brain hyperclassification reveals action-specific motor mapping of observed actions in humans. [PDF]
PLoS ONE, 2017 Seeing an action may activate the corresponding action motor code in the observer. It remains unresolved whether seeing and performing an action activates similar action-specific motor codes in the observer and the actor.

Parametric design of reduced-order functional observers for linear time-varying delay systems
Measurement + Control, 2022 This paper investigates the design of reduced-order functional observer for linear time-invariant systems (LTI) with time-varying delay. Firstly, the sufficient condition for the existence of reduced-order delay-free functional observers is obtained ...

Subjective and objective difficulty of emotional facial expression perception from dynamic stimuli.
PLoS ONE, 2022 This study aimed to discover predictors of subjective and objective difficulty in emotion perception from dynamic facial expressions. We used a multidimensional emotion perception framework, in which observers rated the perceived emotion along a number ...

Observable Structure Functions [PDF]
Kybernetes, 1993 Considers the concept of structure function in reliability theory. Complete lattices are considered in order to model the space of performance levels for both system and components, leading to a general concept of structure function. Measurability with respect to the associate order topology is also assumed.
