CONTROLLER design is more troublesome in aerospace systems due to, inter alia, diversity
of mission platforms, convoluted nonlinear dynamics, predominantly strict mission and …

The smooth variable structure filter (SVSF) is a type of sliding mode filter formulated in a
predictor-corrector format and has seen significant development over the last 15 years. In …

ATTITUDE estimation involves a two-part process: 1) estimation of a vehicle's orientation
from body measurements and known reference observations, such as line-of-sight …

Abstract Integrated MIMU/GNSS/CNS (micro-electro-mechanical system-based inertial
measurement unit/global navigation satellite system/celestial navigation system) is a …

The INS/GNSS integration is the commonly used technique for hypersonic vehicle
navigation. However, owing to the complicated flight dynamics with high maneuverability …

Background As a continuation of our earlier work, we present in this study a Kalman filtering
based algorithm for the elimination of motion artifacts present in Near Infrared spectroscopy …

This paper deals with the problem of state estimation for the integration of an inertial
navigation system (INS) and Global Positioning System (GPS). For a nonlinear system that …

Many controlled systems suffer from unmodeled nonlinear effects that recur periodically over
time. Model-free controllers generally cannot compensate these effects, and good physical …

This paper provides a survey of modern nonlinear filtering methods for attitude estimation.
Early applications relied mostly on the extended Kalman filter for attitude estimation. Since …

As small celestial body exploration advances, higher requirements with regard to system
safety and landing precision are proposed for future landing and sample return missions …
