Contraction-Aware Reinforcement Learning for Nonlinear Control with Statistical Robustness
Quick summary
arXiv:2506.15700v2 Announce Type: replace-cross Abstract: Control contraction metrics (CCMs)-defined by Riemannian metrics under which a closed-loop system is incrementally exponentially stable-offer a constructive framework for synthesizing contracting policies in nonlinear path-tracking problems. However, while the synthesized policies ensure pointwise satisfaction of the CCM conditions, they may not ensure long-term optimality (i.e., minimizing cumulative trajectory-level tracking error) over both transient and steady-state regimes. Furthermore, the myopic nature of these policies could als
