Towards cyber-physical systems robust to communication delays: A differential game approach
Shankar A. Deka, Donggun Lee, Claire J. Tomlin
Collaboration between interconnected cyber-physical systems is becoming increasingly pervasive. Time-delays in communication channels between such systems are known to induce catas…
Lax Formulae for Efficiently Solving Two Classes of State-Constrained Optimal Control Problems
Donggun Lee, Claire J. Tomlin
This paper presents Lax formulae for solving the following optimal control problems: minimize the maximum (or the minimum) cost over a time horizon, while satisfying a state constr…
Hamilton-Jacobi Equations for Two Classes of State-Constrained Zero-Sum Games
Donggun Lee, Claire J. Tomlin
This paper presents Hamilton-Jacobi (HJ) formulations for two classes of two-player zero-sum games: one with a maximum cost value over time, and one with a minimum cost value over…
A Computationally Efficient Hamilton-Jacobi-based Formula for State-Constrained Optimal Control Problems
Donggun Lee, Claire J. Tomlin
This paper investigates a Hamilton-Jacobi (HJ) analysis to solve finite-horizon optimal control problems for high-dimensional systems. Although grid-based methods, such as the leve…
Robust Control Barrier-Value Functions for Safety-Critical Control
Jason J. Choi, Donggun Lee, Koushil Sreenath +2
This paper works towards unifying two popular approaches in the safety control community: Hamilton-Jacobi (HJ) reachability and Control Barrier Functions (CBFs). HJ Reachability ha…
