Observability Analysis of Aided INS With Heterogeneous Features of Points, Lines, and Planes [PDF]
IEEE Transactions on robotics, 2018 In this article, we perform a thorough observability analysis for linearized inertial navigation systems (INS) aided by exteroceptive range and/or bearing sensors (such as cameras, LiDAR, and sonars) with different geometric features (points, lines ...

State Observability through Prior Knowledge: Analysis of the Height Map Prior for Track Cycling
Sensors, 2020 Inertial navigation systems suffer from unbounded errors in the position and orientation estimates. This drift can be corrected by applying prior knowledge, instead of using exteroceptive sensors. We want to show that the use of prior knowledge can yield

Weak observability estimates for 1-D wave equations with rough coefficients [PDF]
, 2013 In this paper we prove observability estimates for 1-dimensional wave equations with non-Lipschitz coefficients. For coefficients in the Zygmund class we prove a "classical" observability estimate, which extends the well-known observability results in ...

Enhancing Observability in Distribution Grids Using Smart Meter Data [PDF]
IEEE Transactions on Smart Grid, 2016 Due to limited instrumentation, distribution grids are currently challenged by observability issues. On the other hand, smart meter data are communicated to utility operators from nodes with renewable generation and elastic demand.

Moving and oblique observations of beams and plates [PDF]
, 2019 We study the observability of the one-dimensional Schr{\"o}dinger equation and of the beam and plate equations by moving or oblique observations. Applying different versions and adaptations of Ingham's theorem on nonharmonic Fourier series, we obtain ...

Asymptotics for optimal design problems for the Schr\"odinger equation with a potential [PDF]
, 2018 We study the problem of optimal observability and prove time asymptotic observability estimates for the Schr\"odinger equation with a potential in $L^{\infty}(\Omega)$, with $\Omega\subset \mathbb{R}^d$, using spectral theory. An elegant way to model the

Exact observability and controllability for linear neutral type systems [PDF]
, 2015 The problem of exact observability is analyzed for a wide class of neutral type systems by an infinite dimensional approach. The duality with the exact controllabil-ity problem is the main tool.

Optimal PMU Placement for Power System Dynamic State Estimation by Using Empirical Observability Gramian [PDF]
, 2014 In this paper the empirical observability Gramian calculated around the operating region of a power system is used to quantify the degree of observability of the system states under specific phasor measurement unit (PMU) placement.
