Introduction to Frequency Domain Analysis

Показать описание
In this video we introduce the concept of frequency domain analysis for a linear dynamic system. At its core, this involves understanding how the system responds to sinusoidal inputs at steady state. We derive the relationship that shows that for a linear system, when it is subjected to a sin wave input, the output at steady state is the same sin wave but the amplitude is modified and the phase is shifted.

Topics and timestamps:
0:00 – Introduction
4:05 – Partial fraction expansion
15:55 – Response of system in time domain
40:56 – Steady state response of system
51:33 – Example
1:01:35 – Summary (single core idea/equation)

Brilliant video, very comprehensive explanation that I haven’t seen before for frequency response. May I ask, is it from a particular textbook or just from your own research/experience. Thanks in advance

AE511: Hey Chris! Some of your videos (including this one) have audio that only comes through one earbud when watching on mobile. Not sure if you’re aware. Maybe it’s the mic setup..? Possible opportunity to improve the channel!
Edit: it does look like when you switch to your pc the audio goes to both channels.

Professor Please make the video on the affect of P and I gain on bode plot. or Please explain me to reply to this comment. My professor said that P gain usually define the magnitude of our controller and I gain make bandwidth only
