3. Mathematically Model Dynamic Systems and Derive Transfer Functions

Dynamic systems react over time to inputs and are described through differential equations. Analyzing these systems involves converting time-domain equations into the frequency domain using transfer functions, which represent the input-output relationship of linear time-invariant systems. The chapter provides the basis for modeling different dynamic systems, deriving their transfer functions, and understanding the relationship between system parameters and behavior.
