BLDC motor speed control using PID

[svraj]

HI all,

I am trying to implement PID algorithm to control speed of bldc motor. For that the RPM of the motor is measured using Hall sensor. Now I have to write the code for pid can anybody tell the logic or example!

I have studied about the PID controller clearly but there is no example for speed control instead lot of example available for position control. In my application the speed is changed using acceleration so when load comes the speed will vary that's why i chose PID

My doubt is:

1. how to assign set point where the acceleration is varying.
2. Should I note down the RPM of the motor at NO load so that it can be used as reference
3. is there any logic to create

#PID #Bldc​
