## Why Padé Approximations Are Great! | Control Systems in Practice

Beginner
Video
Theory

Watch an introduction to Padé approximations. Learn what Padé approximations are and how to calculate them, why they are important, and when to use them—specifically in the context of time...

## Control Systems in Practice, Part 4: Why Time Delay Matters

15 min
Beginner
Video
Theory

Time delays exist in two varieties: signal distorting delays, like phase lag, in which each frequency is delayed by a different amount of time, resulting in a distorted signal shape; and non...

You can skip this reference without getting lost but since I mentioned the step response in the Padé video I thought I'd point you to my Tech Talk video on them. I liked how this video turned out so I'm hoping more people watch it!

## Control Systems in Practice, Part 9: The Step Response

15 min
Beginner
Video
Theory

This video covers a few interesting things about the step response. We’ll look at what a step response is and some of the ways it can be used to specify design requirements for closed loop...

If you want to try out the Padé approximation of time delay with LQR, this video would be a good starting point.

## State Space, Part 4: What is LQR control?

17 min
Beginner
Video
Theory

The Linear Quadratic Regulator (LQR)LQR is a type of optimal control that is based on state space representation. In this video, we introduce this topic at a very high level so that you walk...
