Robust Attitude Control of Nonlinear UAV Dynamics with LFT Models and Performance
Tanay Kumar, Raktim Bhattacharya
Attitude stabilization of unmanned aerial vehicles (UAVs) in uncertain environments presents significant challenges due to nonlinear dynamics, parameter variations, and sensor limi…
Robust Cislunar Navigation via LFT-Based Filtering with Bearing-Only Measurements
Raktim Bhattacharya
This paper develops a robust estimation framework for cislunar navigation that embeds the Circular Restricted Three-Body Problem (CR3BP) dynamics and bearing-only optical measureme…
Sparse Actuation for LPV Systems with Full-State Feedback in Framework
Tanay Kumar, Raktim Bhattacharya
This paper addresses the sparse actuation problem for nonlinear systems represented in the Linear Parameter-Varying (LPV) form. We propose a convex optimization framework that conc…
Optimal Navigation in the Cislunar Space with LFT Models
Tanay Kumar, Raktim Bhattacharya
Navigation in the cislunar domain presents significant challenges due to chaotic and unmodeled dynamics, as well as state-dependent sensor errors. This paper develops a robust esti…
