#28 Tutorial: PID controller using an Arduino

I show how to program a PID controller to be used to stabilize the speed of a motor.
To show the effects of the different factors on the result I test it in reality with the fan of my wind tunnel.

The PID principle can be used for many other applications where unstable systems have to be stabilized.

You explained the details amazingly, definitely enforced my understanding of your project and PID as a whole. Cheers.

Thanks for taking the time to do this, excellent!

Your nice instructive video cured my hang-over. Thanks!

[JohnSmith-edsr]

I understand fully how PID works but lack the understanding of Arduino to implement. Would you be willing to share the code or perhaps a similar bit of code to get us going in the right direction

Eureka! Endlich gschnallt. Danke für die super erklärig.👍👍👍

Wow! Thank you so much for a fascinating and instructive video. I came across you channel purely by chance, but what a wonderful find. I have, of course subscribed, and I hope many more people do too.

Very excellent video and tutorial. Again, I learned something interesting.

thanks a lot, I was struggling with this

I think it was on the boundary of the Arduino to get it higher than Andreas got it. Servo positioning ok. Precise motor control needs a lot more power. My favorite workhorse is a uC from ST Micro. It can do 10 times as much in one tenth the time. Nice tutorial.

Ein Coop Kunde ;-). Wie immer herzlichen Dank und bis zum nächsten Video.

Good video, example code would be a very helpful addition.

Hello. Will you be able to share the code of this fan pid controller. I have made a home made jet engine and this code would be perfect to use as throttle controll. I have a hall sensor with a amplifier and a schmitt trigger so that would be the same as you. Insteed of driving a fan it would be driving the fuelpump. I need this function because today when i am igniting the afterburner the rpm off the engine goes down alitle bit. I have a ordinary 10k potentiometer as throttle.

yeh! this is what I'm looking for! thanks!

Hello and direct one question: Did you use a PID-Library or did you implement that yourself?

[piuselectronics]

what if the motor speed is lower than the required value, wouldn't the P part = current value - required value. Or do I just take the absolute value of the difference

excellente Arbeit. besser hätte man die regler nicht zusammenfassen können ein viedo für ein kamera stabilisation wäre toll :)
