1 | How to simulate a drone motor mathematically

In this video, you will learn how you can simulate a quadcopter drone motor and the gyro sensor mathematically.

The purpose of this video series is to learn the basic mathematics behind a quadcopter drone and enable you to optimise its controls yourself, by dividing this challenging project in several easy-to-understand parts.

I don't like this series.
I love it. There's absolutely nothing like this in the entire YouTube realm!
Thank you man!

This is great. I have built a brushless motor stand that measures thrust and motor RPM (using an IR sensor) instead of measuring the sound of the propeller. This series is a university level introduction to control system dynamics. Many thanks.

Thanks alot for the valuable content! Looking forward for the upcoming parts.

Thank you for showing the speed step response of an ESC with drone. I have been looking for this information.

Are all ESCs sold for drones equally capable of changing the speed fast? Are some ESCs better than others?

I have looked several places for information, and it seems that it is a concern for hobby drone builders to have a fast dynamic regarding speed of the drone motors. I am just surprised to see, that almost none of them measure the step response in order to evaluate that. I have discussed that in a forum, and it was argued, that the sold ESCs for drones the past 10 years already have achieved perfect status, and there is no need to compare ESCs. Do you agree?

Is your ESC used an old ESC, or can it be considered at a modern ESC used for many drones now?

I should guess, that measuring the dynamic speed change of a motor can be done easily in many other ways that using sound.

A fast speed loop is also needed for the motor drive on sewing machines. However this fast response is needed at low speed.

Hi, could You tell me why did you go with that sound based identification (which was very interesting to watch!) instead of logging the accurate data consisting of time, command and thrust using the Teensy?

[fareed]

Hello, thank you for your awesome efforts.
I just wanted to ask, how did you obtain the spectrogram?

[dashs]

This is great stuff. Thanks so much for making all these videos!

[Extner]

Great video! btw kv on the motor does not stand for kilovolts but for the motor's Kv rating.

[AryPizarroChong]

Could you make video of how you build the test cell? I would like to build it myself and draw my own curves! Thanks!

[MrDawen]

could you do a video off how to build the test bench?

[MrViniLP]

Is there a way to contact you?
I have a few questions about how you plotted the sound-data and transformed it.

[Abhishekrai-qilj]

I like your video series. its quite good very well explained with proper logic. Just small correction please check Kv rating its Kv rating not Kilo Volt .
Kv is motor constant that equivalent to rpm/V.

Thank you so much sir... I'm searching for this very long time... Sir can I get complete mathematical model and Transfer function of the quadcopter as soon as possible or atleast as a document

[tomverstappen]

I would like to come in contact with you.
