Reduced-Order and Full-Order Interval Observers Design for Discrete-Time System
IEEE Access, 2020 In this paper, the design of reduced-order and full-order interval observers for discrete-time system is investigated. First, the original system is transformed into a descriptor system with the ability to estimate the unknown noise of sensors.

Complexity, 2022 This work focuses on a multiagent system (MAS) with time-varying interval uncertainty in the system matrix, where multiple agents interact through an undirected topology graph and only the bounding matrices on the uncertainty in the system matrix are ...

Interval observer of minimal error dynamics [PDF]
Automatica, 2020 This paper proposes a simple interval observer which can generate tighter interval estimates of variables in transient states than the standard interval observer. The simple nonlinear dynamics shrinks the estimated intervals to true state variables at the maximum velocity in the absence of disturbances. In the presence of bounded disturbances, ultimate

Principal component analysis for interval‐valued observations [PDF]
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2011 AbstractOne feature of contemporary datasets is that instead of the single point value in thep‐dimensional space ℜpseen in classical data, the data may take interval values thus producing hypercubes in ℜp. This paper studies the vertices principal components methodology for interval‐valued data; and provides enhancements to allow for so‐called ‘trivial’

Delay-dependent positivity: Application to interval observers [PDF]
2015 European Control Conference (ECC), 2015 New delay-dependent conditions of positivity for linear systems with time-varying delays are introduced. These conditions are applied to interval observer design for systems with time-varying delays in the state equations and in the measurements.

On design of sampled-data interval observers [PDF]
2016 European Control Conference (ECC), 2016 New design of interval observers for continuous-time systems with discrete-time measurements is proposed. Positivity and stability conditions are obtained using the time-delay approach. Next, control is synthesized based on interval estimates. Efficiency of the obtained solution is demonstrated on examples.

Nonlocal Electrodynamics of Linearly Accelerated Systems [PDF]
, 2004 The measurement of an electromagnetic radiation field by a linearly accelerated observer is discussed. The nonlocality of this process is emphasized. The nonlocal theory of accelerated observers is briefly described and the consequences of this theory ...

Sampled-data sliding mode observer for robust fault reconstruction: A time-delay approach [PDF]
, 2014 A sliding mode observer in the presence of sampled output information and its application to robust fault reconstruction is studied. The observer is designed by using the delayed continuous-time representation of the sampled-data system, for which ...
