encoder dc motor position control with raspberry pi

Hello.

I have to pid control of the encoder motor position with rasberyy pi. but i don't know how to do it. Requested in the project: If the user enters 10 degrees, the engine will turn 10 degrees and stay there. then it will go to 200 degrees if it enters 200 degrees. I need your help in this regard.

This sounds like a homework question - please correct me if I'm wrong.

You need to describe the hardware a bit better, what kind of motor, how is it controlled by the PI. What kind of position encoder - how is it interfaced to the Pi.

Do you understand the basis of PID control ?

If you fill in these details it may be possible to help you better.

The web is full of stuff about PID motor control, try this for a start:

Sorry - no.

What value is a graduate degree if your thesis is written by some one else ?

I will realize this project and move on to the next step. but I'm stuck here. so it's just part of my thesis. I am a university student and I am aware of my responsibilities. nobody will write my thesis.I just need a little help. thanks.

I have the same problem, I would like to know if it solved it.

I am not sure how to perform the calculation so that it works with PWM.
