Immersion and invariance observer
Witryna11 kwi 2024 · We establish a connection between continuous K-theory and integral cohomology of rigid spaces. Given a rigid analytic space over a complete discretely valued field, its continuous K-groups vanish in degrees below the negative of the dimension. Likewise, the cohomology groups vanish in degrees above the dimension. … Witryna[22] YANG S, AKELLA M R, MAZENC F, Immersion and invariance observers for gyro-free attitude control systems[J].

WitrynaFirst, a coupled linear velocity and angular velocity observer, driven by the spacecraft position and attitude measurements, is designed via the immersion and invariance (I&I) methodology. After dominating the nonlinear terms in the pose dynamics due to rotation motion by high-gain injection, the observer is shown to be exponentially convergent.
