A new empirical study published on arXiv examines the architectural differences between traditional and AI-enabled Simulink controllers used in cyber-physical systems. The research analyzed 62 real-world models and surveyed 13 practitioners, revealing that subsystem organization remains dominant regardless of the controller paradigm. However, AI-enabled controllers heavily utilize discrete dynamics and user-defined abstractions, which are underrepresented in current AI literature. A key finding is the disappearance of explicit constraint enforcement blocks in AI-enabled models, shifting safety mechanisms to implicit training artifacts and potentially breaking traceability. AI
IMPACT Highlights a gap in AI controller design for cyber-physical systems, potentially impacting safety and traceability in future implementations.
