An Equivariant Observer Design for Visual Localisation and Mapping

open access: yes, 2020
This paper builds on recent work on Simultaneous Localisation and Mapping (SLAM) in the non-linear observer community, by framing the visual localisation and mapping problem as a continuous-time equivariant observer design problem on the symmetry group ...

Effective Gibbs State for Averaged Observables

open access: yesEntropy, 2022
We introduce the effective Gibbs state for the observables averaged with respect to fast free dynamics. We prove that the information loss due to the restriction of our measurement capabilities to such averaged observables is non-negative and discuss a thermodynamic role of it.

State estimation method using median of multiple candidates for observation signals including outliers

open access: yesSICE Journal of Control, Measurement, and System Integration, 2021
The state estimation problem for systems in which observation outputs include outliers is addressed herein. When the observation output has outliers, the accuracy of the state estimation is dramatically worse.

On Macroscopic Complexity and Perceptual Coding [PDF]

open access: yes, 2011
The theoretical limits of 'lossy' data compression algorithms are considered. The complexity of an object as seen by a macroscopic observer is the size of the perceptual code which discards all information that can be lost without altering the perception

Quantum Time: experimental multi-time correlations

open access: yes, 2017
In this paper we provide an experimental illustration of Page and Wootters' quantum time mechanism that is able to describe two-time quantum correlation functions.

Three-Dimensional Trajectory Tracking Control of Underactuated AUV Based on Fractional-Order PID and Super-Twisting Extended State Observer

open access: yesFractal and Fractional
This paper addresses the three-dimensional trajectory tracking control problem for the underactuated Autonomous Underwater Vehicle (AUV) operating in complex ocean environments characterized by dynamic disturbances and model uncertainties.

Disturbance modeling and state estimation for offset-free predictive control with state-space process models

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2014
Disturbance modeling and design of state estimators for offset-free Model Predictive Control (MPC) with linear state-space process models is considered in the paper for deterministic constant-type external and internal disturbances (modeling errors). The

Disturbance Observer-Based Robust Model Predictive Control for a Voltage Sensorless Grid-Connected Inverter With an LCL Filter

open access: yesIEEE Access, 2021
This paper proposes a disturbance observer-based robust model predictive control (MPC) for a voltage sensorless grid-connected inverter with an inductive-capacitive-inductive (LCL) filter.

A Hierarchical Observer for a Non–Linear Uncertain CSTR Model of Biochemical Processes

open access: yesInternational Journal of Applied Mathematics and Computer Science
The problem of estimation of unmeasured state variables and unknown reaction kinetic functions for selected biochemical processes modelled as a continuous stirred tank reactor is addressed in this paper.

A Sequential Problem in Decentralized Detection with Communication

open access: yes, 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
