Deep Learning Based Dynamics Identification and Linearization of Orbital Problems using Koopman Theory

no code implementations13 Mar 2024 George Nehma, Madhur Tiwari, Manasvi Lingam

We propose a data-driven framework for simultaneous system identification and global linearization of both the Two-Body Problem and Circular Restricted Three-Body Problem via deep learning-based Koopman Theory, i. e., a framework that can identify the underlying dynamics and globally linearize it into a linear time-invariant (LTI) system.

Computationally Efficient Data-Driven Discovery and Linear Representation of Nonlinear Systems For Control

1 code implementation8 Sep 2023 Madhur Tiwari, George Nehma, Bethany Lusch

This work focuses on developing a data-driven framework using Koopman operator theory for system identification and linearization of nonlinear systems for control.

Adaptive Modified RISE-based Quadrotor Trajectory Tracking with Actuator Uncertainty Compensation

no code implementations17 Mar 2023 Krishna Bhavithavya Kidambi, Madhur Tiwari, Emmanuel Ogbanje Ijoga, William MacKunis

This paper presents an adaptive robust nonlinear control method, which achieves reliable trajectory tracking control for a quadrotor unmanned aerial vehicle in the presence of gyroscopic effects, rotor dynamics, and external disturbances.

SpaceYOLO: A Human-Inspired Model for Real-time, On-board Spacecraft Feature Detection

no code implementations2 Feb 2023 Trupti Mahendrakar, Ryan T. White, Markus Wilde, Madhur Tiwari

Performance in autonomous spacecraft detection of SpaceYOLO is compared to ordinary YOLOv5 in hardware-in-the-loop experiments under different lighting and chaser maneuver conditions at the ORION Laboratory at Florida Tech.
