Sparse Sensing and Optimal Precision: Robust Optimal Observer Design with Model Uncertainty
Vedang M. Deshpande, Raktim Bhattacharya
We present a framework which incorporates three aspects of the estimation problem, namely, sparse sensor configuration, optimal precision, and robustness in the presence of model u…
A Lagrangian Method for Constrained Dynamics in Tensegrity Systems with Compressible Bars
Shao-Chen Hsu, Vaishnav Tadiparthi, Raktim Bhattacharya
This paper presents a Lagrangian approach to simulating multibody dynamics in a tensegrity framework with an ability to tackle holonomic constraint violations in an energy-preservi…
Modeling and Optimal Control of Hybrid UAVs with Wind Disturbance
Sunsoo Kim, Niladri Das, Raktim Bhattacharya
This paper addresses modeling and control of a six-degree-of-freedom unmanned aerial vehicle capable of vertical take-off and landing in the presence of wind disturbances. We desig…
A unified framework to generate optimized compact finite difference schemes
Vedang M. Deshpande, Raktim Bhattacharya, Diego A. Donzis
A unified framework to derive optimized compact schemes for a uniform grid is presented. The optimal scheme coefficients are determined analytically by solving an optimization prob…
Privacy and Utility Aware Data Sharing for Space Situational Awareness from Ensemble and Unscented Kalman Filtering Perspective
Niladri Das, Raktim Bhattacharya
In this paper, we present an optimization-based formulation for privacy-utility tradeoff in the Ensemble and Unscented Kalman filtering framework, with a focus on space situational…
Surrogate Modeling of Dynamics From Sparse Data Using Maximum Entropy Basis Functions
Vedang M. Deshpande, Raktim Bhattacharya
In this paper we present a data driven approach for approximating dynamical systems. A dynamics is approximated using basis functions, which are derived from maximization of the in…
