Transfer Function and Bode Plots

By pianoforte · Last updated: October 18, 2026 · Created: October 18, 2026

Pretty much everything involved in control systems works in Laplace Space – we are working in the frequency domain! Transfer functions in control systems are in the Laplace space, and tell us the relationship between the system input and outputs.

For a general understanding of transfer functions, please read the following excerpt:

Laplace Transform:

Bode Plots:

For a more in-depth explanation regarding transfer function and the Laplace transform, block diagrams, and an introduction to Bode plots, see the following textbook excerpt. Please note that there is a lot of theory in here – you don’t need to understand everything, nor do you have to read every section. Just skim over it and look for the keywords:
