Derivative-Free Observability Analysis for Sensor Placement Optimization of Bioinspired Flexible Flapping Wing System

open access: yesBiomimetics, 2022
Observability analysis of a bioinspired flexible flapping wing system provides a measure of how well the states of flexible flapping wing micro-aerial vehicles can be estimated from real-time measurements during high-speed flight.

Observability Analysis and Improvement Approach for Cooperative Optical Orbit Determination

open access: yesAerospace, 2022
Cooperative orbit determination (OD) using inter-spacecraft optical measurements is an important technology for space constellation missions. In this paper, the observability of a two-spacecraft cooperative OD system is investigated.

Observable space of the nonlinear control system on a homogeneous time scale; pp. 11–25 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
The observability property of the nonlinear system, defined on a homogeneous time scale, is studied. The observability condition is provided through the notion of the observable space.

Improved Observability in Distribution Grids Using Correlational Measurements

open access: yesIEEE Access, 2022
This paper develops a novel pseudo-measurement construct termed a Correlational Measurement (CM) to improve observability and state estimation accuracy. CMs utilize the correlation between similar classes of loads and DERs.

Dynamic Intransitive Noninterference Model Based on iP-observability Attribute [PDF]

open access: yesJisuanji gongcheng, 2018
In order to solve the problem that the existing information flow model is too strict to determine the dynamic trusted of system,a dynamic Intransitive Noninterference(INI) model based on iP-observability attribute checking is proposed.It abstracts the ...

Observability Transitions in Networks with Betweenness Preference. [PDF]

open access: yesPLoS ONE, 2016
A network is considered observable if its current state can be determined in finite time from knowledge of the observed states. The observability transitions in networks based on random or degree-correlated sensor placement have recently been studied ...
