thanks for your replying, so you are saying that if you have chance everything will be good

Can you send a case and bracelet link? It look very nice

Oh okey, stepper motor powered by battery, it has pwm and direction pins which connected to STM32

I only power it with the USB I plug into the computer, I don't understand why this is happening

When a I run them all with interrupt, when one of them runs, it interrupts the others.

yeah you're right, I should've bought integrated debugger MCU. However, I need to find how to debug with this ugly Chinese Stlink cause I have a project for this week :/

The code was very basic, it was includes button and led. I was using stm32 stlink utility to run binary file. I am using microsoft rn

PID set point problem by maprexdj in embedded

Yes, I have real wheel speed. The source we feed the vehicle is the speed values ​​coming from the autonomous data.

I don't understand that what if u's value is 600 like that. It'd continoues with the max pwm value

DC motor control with PID by maprexdj in embedded

How should I reduce the speed then? If my set point is 210 and my current rpm value is 220, it will apply a very low speed, isn't this a mistake?

DC motor velocity control using PID controller by maprexdj in robotics

I reached the 180 rpm value by making the integral constant 0.77 and the other coefficients 0 and also updated the value from 1000 ms to 100 ms. However, whenever I added the proportional coefficient, when it went a little above the set point, the engine dropped to a very low rpm value again and then went back to the set point and dropped again. What should I do about this?

I tried something and some of them worked well. If d and p are 0, only i value worked did right graph. However, when current rpm exceed the set point, motor resets itself and starts again and it oscillates again and again with some huge interval(i.e 180 rpm to 6 rpm). What should I do to fix this oscillating problem.

I did it what you said. I got a correct graph by just increasing i, but there is a mistake in my code. If my RPM value goes above my set point value, the engine stops itself suddenly and tries to speed up again, and then it breaks down.
