# 10.3 Linearized models

## Description

March 27, 2021

In this lecture, we will learn:

- We can linearize a nonlinear dynamic model, just as we do for functions.
- A linearized, averaged model is a linear time-invariant (LTI) system and applying LTI control theory is valid.
- The validity of the model is limited to small perturbations and slowly variations; still, the model is surprisingly forgiving.
