Provably Robust Learning-Based Approach for High-Accuracy Tracking Control of Lagrangian Systems

RA-L 2019

Lagrangian systems represent a wide range of robotic systems, including manipulators, wheeled and legged robots, and quadrotors. Inverse dynamics control and feedforward linearization are typically used to convert the complex nonlinear dynamics of Lagrangian systems to a set of decoupled double inte

An Inversion-Based Learning Approach for Improving Impromptu Trajectory Tracking of Robots With Non-Minimum Phase Dynamics

RA-L 2018

This letter presents a learning-based approach for impromptu trajectory tracking for non-minimum phase systems, i.e., systems with unstable inverse dynamics. Inversion-based feedforward approaches are commonly used for improving tracking performance; however, these approaches are not directly applic

Data-Efficient Multirobot, Multitask Transfer Learning for Trajectory Tracking

RA-L 2018

Transfer learning has the potential to reduce the burden of data collection and to decrease the unavoidable risks of the training phase. In this letter, we introduce a multirobot, multitask transfer learning framework that allows a system to complete a task by learning from a few demonstrations of a

Deep neural networks for improved, impromptu trajectory tracking of quadrotors

ICRA 2017poster

Trajectory tracking control for quadrotors is important for applications ranging from surveying and inspection, to film making. However, designing and tuning classical controllers, such as proportional-integral-derivative (PID) controllers, to achieve high tracking precision can be time-consuming an…
