Semi-global Exponential Stability for Dual Quaternion Based Rigid-Body Tracking Control

no code implementations24 May 2023 Vrushabh Zinage, S P Arjun Ram, Maruthi R. Akella, Efstathios Bakolas

Semi-Global Exponential Stability (SGES) is proved for the combined attitude and position rigid body motion tracking problem, which was previously only known to be asymptotically stable.

Feedback Strategies for Hypersonic Pursuit of a Ground Evader

no code implementations18 Nov 2021 Yoonjae Lee, Efstathios Bakolas, Maruthi R. Akella

Subsequently, using this linearized system model, we formulate an auxiliary two-player zero-sum LQDG which is effective in the neighborhood of the given reference trajectory and derive its feedback saddle point strategy that allows the hypersonic vehicle to modify its trajectory online in response to the target's evasive maneuvers.

Riemannian Trust-Region based Adaptive Kalman filter with unknown noise Covariance matrices

no code implementations24 Apr 2021 Rahul Moghe, Maruthi R. Akella, Renato Zanetti

The problem of adaptive Kalman filtering for a discrete observable linear time-varying system with unknown noise covariance matrices is addressed in this paper.

Real-Time, Flight-Ready, Non-Cooperative Spacecraft Pose Estimation Using Monocular Imagery

no code implementations23 Jan 2021 Kevin Black, Shrivu Shankar, Daniel Fonseka, Jacob Deutsch, Abhimanyu Dhir, Maruthi R. Akella

A key requirement for autonomous on-orbit proximity operations is the estimation of a target spacecraft's relative pose (position and orientation).
