Data-Driven Control with Inherent Lyapunov Stability

no code implementations6 Mar 2023 Youngjae Min, Spencer M. Richards, Navid Azizan

Recent advances in learning-based control leverage deep function approximators, such as neural networks, to model the evolution of controlled dynamical systems over time.

Learning Control-Oriented Dynamical Structure from Data

1 code implementation6 Feb 2023 Spencer M. Richards, Jean-Jacques Slotine, Navid Azizan, Marco Pavone

Even for known nonlinear dynamical systems, feedback controller synthesis is a difficult problem that often requires leveraging the particular structure of the dynamics to induce a stable closed-loop system.

A System-Level View on Out-of-Distribution Data in Robotics

no code implementations28 Dec 2022 Rohan Sinha, Apoorva Sharma, Somrita Banerjee, Thomas Lew, Rachel Luo, Spencer M. Richards, Yixiao Sun, Edward Schmerling, Marco Pavone

When testing conditions differ from those represented in training data, so-called out-of-distribution (OOD) inputs can mar the reliability of learned components in the modern robot autonomy stack.

Adaptive Robust Model Predictive Control via Uncertainty Cancellation

no code implementations2 Dec 2022 Rohan Sinha, James Harrison, Spencer M. Richards, Marco Pavone

We propose a learning-based robust predictive control algorithm that compensates for significant uncertainty in the dynamics for a class of discrete-time systems that are nominally linear with an additive nonlinear component.

Meta-Learning Model Predictive Control

Control-oriented meta-learning

1 code implementation14 Apr 2022 Spencer M. Richards, Navid Azizan, Jean-Jacques Slotine, Marco Pavone

Real-time adaptation is imperative to the control of robots operating in complex, dynamic environments.

Adaptive Robust Model Predictive Control with Matched and Unmatched Uncertainty

no code implementations16 Apr 2021 Rohan Sinha, James Harrison, Spencer M. Richards, Marco Pavone

We propose a learning-based robust predictive control algorithm that compensates for significant uncertainty in the dynamics for a class of discrete-time systems that are nominally linear with an additive nonlinear component.

Adaptive-Control-Oriented Meta-Learning for Nonlinear Systems

1 code implementation7 Mar 2021 Spencer M. Richards, Navid Azizan, Jean-Jacques Slotine, Marco Pavone

Real-time adaptation is imperative to the control of robots operating in complex, dynamic environments.

Learning Stabilizable Nonlinear Dynamics with Contraction-Based Regularization

1 code implementation29 Jul 2019 Sumeet Singh, Spencer M. Richards, Vikas Sindhwani, Jean-Jacques E. Slotine, Marco Pavone

We propose a novel framework for learning stabilizable nonlinear dynamical systems for continuous control tasks in robotics.

Continuous Control

The Lyapunov Neural Network: Adaptive Stability Certification for Safe Learning of Dynamical Systems

1 code implementation2 Aug 2018 Spencer M. Richards, Felix Berkenkamp, Andreas Krause

We demonstrate our method by learning the safe region of attraction for a simulated inverted pendulum.
