This chapter has been split into focused sections for better learning:
Topics: What is a Process and System, Block Diagrams, IoT System Decomposition Time: ~15 min | Level: Foundational
Learn the fundamental concepts of processes and systems in IoT architectures. Understand how electronic systems transform inputs into outputs through controlled processes using block diagram representations.
Key Topics: - Process vs System definitions - Block diagram representation - Coffee pot system example - Hierarchical system decomposition - Design considerations
Topics: Feedback Loops, Electronic Feedback Systems, Smart Home Examples Time: ~20 min | Level: Intermediate
Explore how feedback mechanisms enable systems to self-regulate and maintain desired behaviors. See real-world examples including smart home heating and automatic clothes dryers.
Key Topics: - Feedback fundamentals - Negative vs positive feedback - Electronic feedback systems - Smart home heating system - Automatic clothes dryer example
Topics: Control System Types, Trade-offs, Water Quality Monitoring Time: ~12 min | Level: Intermediate
Compare open-loop and closed-loop control systems, understanding their advantages, limitations, and appropriate use cases in IoT applications.
Key Topics: - Open-loop systems (characteristics, advantages, limitations) - Closed-loop systems (characteristics, advantages, limitations) - Trade-off comparisons - Water quality monitoring example
Topics: PID Theory, Tuning, Hands-On Labs, Implementation Time: ~45 min | Level: Advanced
Master Proportional-Integral-Derivative (PID) control theory and implementation. Learn about P-only limitations, integral windup, derivative action, and practical tuning techniques.
Key Topics: - PID fundamentals (P, I, D terms) - Home temperature control example - P-only control and steady-state error - Integral windup problem - Derivative action and noise sensitivity - Hands-on PID simulation lab - Python implementation - Production frameworks
