Data-Driven Chance Constrained Control using Kernel Distribution Embeddings
Adam J. Thorpe, Thomas Lew, Meeko M. K. Oishi +1
We present a data-driven algorithm for efficiently computing stochastic control policies for general joint chance constrained optimal control problems. Our approach leverages the t…
A Simple and Efficient Sampling-based Algorithm for General Reachability Analysis
Thomas Lew, Lucas Janson, Riccardo Bonalli +1
In this work, we analyze an efficient sampling-based algorithm for general-purpose reachability analysis, which remains a notoriously challenging problem with applications ranging…
On the Problem of Reformulating Systems with Uncertain Dynamics as a Stochastic Differential Equation
Thomas Lew, Apoorva Sharma, James Harrison +2
We identify an issue in recent approaches to learning-based control that reformulate systems with uncertain dynamics using a stochastic differential equation. Specifically, we disc…
Control Barrier Functions for Cyber-Physical Systems and Applications to NMPC
Jan Schilliger, Thomas Lew, Spencer M. Richards +3
Tractable safety-ensuring algorithms for cyber-physical systems are important in critical applications. Approaches based on Control Barrier Functions assume continuous enforcement,…
Sampling-based Reachability Analysis: A Random Set Theory Approach with Adversarial Sampling
Thomas Lew, Marco Pavone
Reachability analysis is at the core of many applications, from neural network verification, to safe trajectory planning of uncertain systems. However, this problem is notoriously…
