Data-Driven Control with Inherent Lyapunov Stability

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. However,…

Learning Control-Oriented Dynamical Structure from Data

Spencer M. Richards, Jean-Jacques Slotine, Navid Azizan +1

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…

Adaptive Robust Model Predictive Control via Uncertainty Cancellation

Rohan Sinha, James Harrison, Spencer M. Richards +1

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…

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

Rohan Sinha, Apoorva Sharma, Somrita Banerjee +6

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…

Control-oriented meta-learning

Spencer M. Richards, Navid Azizan, Jean-Jacques Slotine +1

Real-time adaptation is imperative to the control of robots operating in complex, dynamic environments. Adaptive control laws can endow even nonlinear systems with good trajectory…

Learning Stabilizable Nonlinear Dynamics with Contraction-Based Regularization

Sumeet Singh, Spencer M. Richards, Vikas Sindhwani +2

We propose a novel framework for learning stabilizable nonlinear dynamical systems for continuous control tasks in robotics. The key contribution is a control-theoretic regularizer…
