Digital implementation of continuous-time observers for nonlinear networked control systems
SICE Journal of Control, Measurement, and System Integration, 2021 We propose a digital implementation of continuous-time observers to networked control systems. We introduce a sufficiently small constant time step to construct the Euler model of continuous-time observers parameterized by this time step.

Model-Based Observer Design Considering Unequal Measurement Delays
Actuators, 2021 State observers are essential components of a modern control system. It is often designed based on a mathematical model of the process, thus requiring detailed process knowledge.

Physical observers, T-vacuum and Unruh like effect in the radiation dominated early universe
Journal of High Energy Physics, 2020 We report the existence of an Unruh like effect, for physical observers (cosmo- logical and comoving observers) in the radiation dominated early universe, which is possible due to the discovery of a new vacuum state (referred here as the T−vacuum).

Load Torque Observer for BLDC Motors Based on a HOSM Differentiator
Machines, 2023 An observer is proposed for a trapezoidal brushless DC motor composed of a cascade connection of a reduced-order Luenberger observer and a high-order sliding mode (HOSM) differentiator. This configuration can estimate the angular velocity and reconstruct

Non-Recursive Fixed-Time Convergence Observer and Extended State Observer
IEEE Access, 2018 In this paper, non-recursive fixed-time convergence (FxTC) observers were proposed to deal with missions, such as state estimation and tracking differentiation. The observers were designed based on the time-scale paradigm, such that the parameters tuning

State estimation for MISO non–linear systems in controller canonical form
International Journal of Applied Mathematics and Computer Science, 2016 We propose a new observer where the model, decomposed in generalized canonical form of regulation described by Fliess, is dissociated from the part assuring error correction.

Synchronization control of fractional order linear systems based on state estimation
Nantong Daxue xuebao. Ziran kexue ban, 2023 This study focuses on the synchronization control of a class of fractional-order linear systems with orders between(1, 2), based on state observers. State observers and feedback controllers are designed to estimate the unknown states of the response ...

State and Unknown Terrain Estimation for Planetary Rovers via Interval Observers
Advanced Intelligent Systems, 2023 Herein, the problem of state and unknown terrain estimation is considered, where the unknown planetary terrain parameters, e.g., terrain stiffness and ground height, are inferred from how it affects rover motion through vehicle‐terrain interaction.
