Left-invariant extended Kalman filter and attitude estimation

TLDR
A left- invariant (i.e, intrinsic and thus symmetry-preserving) extended Kalman filter such that the left-invariant estimation error obeys a stochastic differential equation independent of the system trajectory.
Abstract
We consider a left-invariant dynamics on a Lie group. One way to define driving and observation noises is to make them preserve the symmetries. We propose a left- invariant (i.e, intrinsic and thus symmetry-preserving) extended Kalman filter such that the left-invariant estimation error obeys a stochastic differential equation independent of the system trajectory. The theory is illustrated by an attitude estimation example.

Invariant Extended Kalman Filter: theory and application to a velocity-aided attitude estimation problem

TL;DR: A new version of the extended Kalman filter (EKF) is proposed for nonlinear systems possessing symmetries, which uses a geometrically adapted correction term based on an invariant output error to result in a better convergence of the estimation.

Complementary filter design on the special orthogonal group SO(3)

TL;DR: In this article, two different non-linear complementary filters are proposed: Direct complementary filter and Passive nonlinear complementary filter, which evolve explicity on the special orthogonal group SO(3) and can be expressed in quaternion form for easy implementation.

Symmetry-Preserving Observers

TL;DR: Using the theory of invariant observers, i.e, symmetry-preserving observers, three non-linear observers are built for three examples of engineering interest: a non-holonomic car, a chemical reactor, and an inertial navigation system.
