A couple of months of my graduate course in just 10 minutes! :-D ... Thanks for sharing!

I looked into it a bit more, the disadvantage of this method is that it is only looking for encoder A pin rising. This means that wiggling the motor back and forth a little looks like the motor is moving continuously forwards. It also counts more than one step if the input bounces. Instead: checking for all four quadrature transitions fixes these problems and means 4x as many pulses per rotation which means you can be more precise. I added these lines at the beginning: #define readA bitRead(PIND,2)//faster than digitalRead() #define readB bitRead(PIND,3)//faster than digitalRead() I changed the attachInterrupt line so that it triggered on CHANGE rather than rising, and added another line for the B encoder pin: attachInterrupt(digitalPinToInterrupt(ENCA),readEncoderA,CHANGE); attachInterrupt(digitalPinToInterrupt(ENCB),readEncoderB,CHANGE); And I changed the functions triggered by the interrupt to this: void readEncoderA(){ if(readB != readA) { posi ++; } else { posi --; } } void readEncoderB(){ if (readA == readB) { posi ++; } else { posi --; } } This eliminates bouncing (posi will just count forwards and then backwards with each bounce), increases precision as you get 4x as many interrupts triggered per rotation, and prevents you from 'tricking' the encoder by moving the motor back and forth by a small amount.

You can set a interrupt on both pins and use it to access a lookup table. As a bonus, this can achieve full resolution of encoder.

One of the best videos I have come across. The combination of the hardware setup and linking this to the block diagram and finally linking block diagram to code is an inspiring idea.

Hi @@curiores111 , the scope of this video is perfect. If you had a feeling that it was too much, perhaps for a beginner it may be too much. For someone that already has a basic understanding and some experience coding it's absolutely perfect!! So well done!! Thank you so much.

This is a great tutorial: short and very precise explanation, yet covering a vast area on the subject. Pleaee make more videos like this.

This, in comparison with many other videos on the subject, is very well done!

Whole PID, encoder, Basic control theory with real applications under 10 minutes. Thank you and you are very well on educating.

Nice combination of electronics, maths and programming. I'd come across those PID values in my Sitech motor controller and now I know what they are ! Thanks for clear presentation and explanation.

The near-perfect tutorial. Clear, concise, the animations are fluid and easy to understand, and straight to the point. Nice!

I just discovered your channel -- it's fantastic! I appreciate your clarity, pace, and your choice of what to focus on in each video. I hope there will be more videos in the future!

Extremely well done. Have been utilizing an adaption of this PID control loop for leveling. Instead of using an encoder I pull data from a MPU6050 using the MPU6050_light library usually included in the Arduino IDE. Then Set the target to 0. It works really well!

I have to commend you on the best tutorial I have seen on motor control using PID! As others have mentioned you are clear concise and to the point. Your animations and diagrams support your lecture perfectly. Your progressive coding makes it easy to understand your logic flow....given the real world, converted to math, and then to software. Kudos!

Finally I came across your video and this was poor luck because my search on youtube gave nothing like yours. So thank you very much for taking your time to explain all of this. I like control theory because it´s hard to understand but If you understand it makes you proud.

Theory is dry but what you show makes more fun at least :D Hey I have an idea do you think an encoder attached to a bldc motor would allow me to set the motor speed perfectly with your pid method ? I have such a motor left from an old hdd and I would play around with your code. I only knew how to do it with op amps but changing code is faster than changing capacitors and resistors.

one of the most useful videos about the dc motor position control! thank you.

Great video tutorial! A lot of the PC CNC controllers have step and direction outputs for stepper motor drives, thought it might be pretty easy, if another interrupt is available, to change the setpoint based on step and direction inputs, should be superior to a stepper motor because of the closed loop.

I need more videos.It's awesome.

Very nice video, and close to what I'm looking at doing. My plans so far will be with any Arduino board, I'm wanting to have a AS5600 read a direction/step every second and write/save that info, so an average can be calculated for later use. Then once a minute or so read another AS5600 with a Stepper motor and have the stepper match the average direction/steps of the other one.

Excellent, I just finished following your tutorial and everything worked out great. Still playing with the PID values to get the sinus as close as possible to the target but I think the motor just isn't precise enough.

@curiores111

3 жыл бұрын

Good work! Using a motor with a higher gear ratio will help with precision. (of course, if you need much better precision a stepper is often a better choice) Adjusting the PID parameters can help, but won't be able to overcome some of the limitations of the motor, as you're finding.

Thank you for the video its really very helpful
