What Is Linearization?

Why go through the trouble of linearizing a model? To paraphrase Richard Feynman, it’s because we know how to solve linear systems. With a linear model we can more easily design a controller, assess stability, and understand the system dynamics.

This video introduces the concept of linearization and covers some of the topics that will help you understand how linearization is used and why it’s helpful.

This video also describes operating points and the process of trimming your system to make an operating point an equilibrium. To end, we walk through an example of Jacobian linearization by looking at the first order partial derivatives of a system.
