Compactly Restrictable Metric Policy Optimization Problems

no code implementations12 Jul 2022 Victor D. Dorobantu, Kamyar Azizzadenesheli, Yisong Yue

We study policy optimization problems for deterministic Markov decision processes (MDPs) with metric state and action spaces, which we refer to as Metric Policy Optimization Problems (MPOPs).

Continuous Control

Safety of Sampled-Data Systems with Control Barrier Functions via Approximate Discrete Time Models

no code implementations22 Mar 2022 Andrew J. Taylor, Victor D. Dorobantu, Ryan K. Cosner, Yisong Yue, Aaron D. Ames

Existing design paradigms do not address the gap between theory (controller design with continuous time models) and practice (the discrete time sampled implementation of the resulting controllers); this can lead to poor performance and violations of safety for hardware instantiations.

Towards Robust Data-Driven Control Synthesis for Nonlinear Systems with Actuation Uncertainty

no code implementations21 Nov 2020 Andrew J. Taylor, Victor D. Dorobantu, Sarah Dean, Benjamin Recht, Yisong Yue, Aaron D. Ames

Modern nonlinear control theory seeks to endow systems with properties such as stability and safety, and has been deployed successfully across various domains.

A Control Lyapunov Perspective on Episodic Learning via Projection to State Stability

no code implementations18 Mar 2019 Andrew J. Taylor, Victor D. Dorobantu, Meera Krishnamoorthy, Hoang M. Le, Yisong Yue, Aaron D. Ames

The goal of this paper is to understand the impact of learning on control synthesis from a Lyapunov function perspective.

Episodic Learning with Control Lyapunov Functions for Uncertain Robotic Systems

no code implementations4 Mar 2019 Andrew J. Taylor, Victor D. Dorobantu, Hoang M. Le, Yisong Yue, Aaron D. Ames

Many modern nonlinear control methods aim to endow systems with guaranteed properties, such as stability or safety, and have been successfully applied to the domain of robotics.
