On Sliding Mode Observers for Systems with Unknown Inputs [PDF]

open access: yes, 2007
International audienceThis paper considers the problem of designing an observer for a linear system subject to unknown inputs. This problem has been extensively studied in the literature with respect to both linear and nonlinear (sliding mode) observers.

Personalised ecology and detection functions

open access: yesPeople and Nature, 2020
Direct interactions with nature are important for people's health, well‐being and support for pro‐nature policies. There is an urgent need better to understand the structure and dynamics of these interactions, and how they differ among individual people,

HD 66051, an eclipsing binary hosting a highly peculiar, HgMn-related star

open access: yesScientific Reports, 2017
HD 66051 is an eclipsing system with an orbital period of about 4.75 d that exhibits out-of-eclipse variability with the same period. New multicolour photometric observations confirm the longevity of the secondary variations, which we interpret as a ...

Reconstructing initial data using observers: error analysis of the semi-discrete and fully discrete approximations [PDF]

open access: yes, 2010
A new iterative algorithm for solving initial data inverse problems from partial observations has been recently proposed in Ramdani et al. (Automatica 46(10), 1616-1625, 2010 ).

Virtual Diagnostic Sensors Design for an Automated Guided Vehicle

open access: yesApplied Sciences, 2018
In recent years, Automated Guided Vehicles (AGVs) have been playing an increasingly important role in producing industry and infrastructure and will soon arrive to other areas of human life such as the transportation of goods and people. However, several

Observations on the observer pattern [PDF]

open access: yesProceedings of the 17th Conference on Pattern Languages of Programs, 2010
A group of students who should have been familiar with basic design principles and MVC all failed to implement the Observer design pattern correctly while at the same time violating several design principles. This paper discusses what went wrong and why it probably went wrong.

On output feedback nonlinear model predictive control using high gain observers for a class of systems [PDF]

open access: yes, 2001
In recent years, nonlinear model predictive control schemes have been derived that guarantee stability of the closed loop under the assumption of full state information.
