02_control / Control & AITL Article Index

This directory systematically organizes articles on
PID control, FSM, and AITL (Architecture for Integrated Technology Logic),
covering control theory, reliability-oriented design, safety boundaries,
and human-centered design philosophy.

🧭 Architectural Positioning

• PID: Inner real-time stabilization loop
• FSM: Supervisory layer for modes and state transitions
• AITL (LLM): Redesign and reconfiguration layer for anomalies and degradation

Control is not about making systems stronger,
but about designing how they fail safely.
