🎛️ 02_control / Control & AITL Article Index

This directory organizes articles around
PID control, FSM, and AITL (Architecture for Integrated Technology Logic).

The focus is not control performance itself,
but the structure of control, including:

• reliability-oriented design
• safety boundaries
• limits of applicability
• and the role of human judgment

This series does not aim to make control stronger.
It aims to define where control holds, and where it must stop.

📘 Fundamental Structure & Philosophy

This section defines the basic structure of AITL control and the assumptions behind conventional control designs.

• 01 AITL Controller Overview
• 02 Why FSM Control Often Fails
• 03 PID Control Is Stronger Than Expected

🛡 Reliability Control & Design Limits

This section focuses on control failure that occurs even when stability appears to be maintained.

• 04 Reliability Control Beyond Robust Control
• 05 Why Reliability Control Fails at Timing
• 06 Reliability FSM in AITL

🔮 Future Design Directions & Control Classification

This section introduces control classification to clarify where different control approaches apply.

• 07 B-Type Control and Future Direction

⚙ PID × FSM Integrated Design

This section covers control structures that remain valid at the implementation level.

• 08 PID–FSM 10% Threshold Design
• 09 Final AITL PID–FSM Design Based on Human Judgment
• 10 Envelope Design and Recovery Strategy

🚧 A-Type / B-Type Control Constraints

This section explicitly defines what control cannot do.

• 11 Limits of A-Type Control
• 12 B-Type Control Guard Design
• 13 FSM Reliability Guard

🔒 Safety Boundaries & Packaging

This section defines boundaries required to make control deployable as a system.

• 14 AITL Controller Reliability Boundary
• 15 AITL Controller Safety Package (Initial Edition)
• 16 AITL Controller Safety Package (Integrated Edition)

🧾 Summary — Design Specifications

This section serves as a reference for understanding the overall architecture.

• 17 AITL Control Architecture Specification
• 18 AI Control Safety Design Checklist (Operational Use)
• 19 Applicability Limits of Adaptive Control (A-Type / B-Type)

🧭 Architectural Positioning

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

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