8. Design PID Controllers for Dynamic Systems
Control systems are categorized into different types based on their mathematical properties, structure, and behavioral aspects—most notably linear vs. non-linear systems and analog vs. digital systems. Linear systems exhibit predictable relationships between input and output, while non-linear systems present complex dynamics. Analog systems operate with continuous signals, while digital systems utilize discrete ones, each with specific advantages and applications. Understanding these classifications is essential for selecting appropriate control methods in various engineering applications.

What we have learnt
- Control systems are classified into linear vs. non-linear and analog vs. digital categories.
- Linear control systems rely on the superposition principle and exhibit predictable behavior.
- Non-linear control systems display complex behaviors with no simple additive outputs.
Key Concepts
- -- Linear Control Systems
- Systems where the output is a linear function of the input, allowing for predictable responses.
- -- NonLinear Control Systems
- Systems where the relationship between input and output is not proportional or additive, leading to complex responses.
- -- Analog Control Systems
- Systems that utilize continuous signals representing inputs and outputs.
- -- Digital Control Systems
- Systems that represent inputs and outputs as discrete signals processed by digital processors.
