A Novel Case of Practical Exponential Observer Using Extended Kalman Filter [PDF]

, 2018
This technical note presents a case of practical exponential observer using extended Kalman filter (EKF) independent of certain restrictions, such as online check and estimation error of initial state.

Back(reaction) to the Future in the Unruh-de Sitter State [PDF]

, 2019
Motivated by black hole physics, we define the Unruh state for a scalar field in de Sitter space. Like the Bunch-Davies state, the Unruh-de Sitter state appears thermal to a static observer.

Sensorless Control of CSI-Fed PMSM Drives Based on Improved Extended State Observer

Energies
To address the problem that the maximum error of back-EMF observers increases with an increase in motor speed, based on an extended state observer, this paper designs an angle-compensation strategy based on a proportional–integral controller and an ...

A Sequential Problem in Decentralized Detection with Communication

, 2009
A sequential problem in decentralized detection is considered. Two observers can make repeated noisy observations of a binary hypothesis on the state of the environment. At any time, observer 1 can stop and send a final binary message to observer 2 or it

A Neural Network Perspective to Extended Luenberger Observers

Measurement + Control, 2002
In this paper we investigate the use of adaptive extended Luenberger state estimators for general nonlinear and possibly time-varying systems. We identify the connection between the extended Luenberger observer and Grossberg's additive model for dynamic ...

Second-Order Fault Tolerant Extended Kalman Filter for Discrete Time Nonlinear Systems [PDF]

, 2019
As missing sensor data may severely degrade the overall system performance and stability, reliable state estimation is of great importance in modern data-intensive control, computing, and power systems applications.

Robust fault estimation and fault-tolerant control for nonlinear Markov jump systems with time-delays

Automatika, 2021
The problem of the robust fault estimation and robust fault-tolerant control, for a class of nonlinear time-delayed Markov jump systems (MJSs) with both actuator and sensor faults, was studied.
