AI Decoded: Cyber-Physical Systems & Edge Intelligence (Part 20)

Introduction

As industries embrace digital transformation, Cyber-Physical Systems (CPS) — integrating computation, networking, and physical processes — form the backbone of modern automation (GlobeNewswire).

Edge Intelligence brings AI inference and learning closer to devices and sensors, reducing latency and data transmission while preserving privacy (IoT For All).

Foundations of Edge Intelligence in CPS

Edge Intelligence in CPS leverages specialized hardware accelerators and compact ML models colocated with control units to enable instant decision-making (MIT Press).

Key design principles include distributed ML orchestration, secure data pipelines, and on-device model updates via federated learning frameworks (Emerald Insight).

Platforms & Frameworks

• Azure IoT Edge — AI on IoT devices with cloud integration
• AWS IoT Greengrass — Extends AWS to edge devices
• TensorFlow Lite — Lightweight on-device inference
• PyTorch Mobile — Deploy PyTorch models on mobile and edge
• Flower — Federated learning framework for edge AI

Security & Reliability

CPS security demands encrypted communications, anomaly detection, and device authentication to prevent cyber-physical attacks (Satellite Today).

Anomaly-based monitoring using AI models helps flag deviations in sensor data and control commands, improving resilience against intelligent threats (Asia Research News).

Case Study: Predictive Maintenance

An automotive plant deployed an Edge AI system processing vibration and temperature data locally to predict failures, cutting unplanned downtime by 30% and maintenance costs by 25% (Wevolver).
