macher WROTE:Another issue is that i don't understand why do we limit the P,I,D values to 100 in PR24,
can anyone please tell me why?
There is no specific reason for this. We did it is merely for the ease of calculation. You are free to modify that as you like.
can this PID controller be applied to any dc motor, working with 12v? How will i measure the control parameters, such as settlingtime, overshoot, damping of the response? since there are no motor parameters, i just can't calculate them so depending on what will i give the P, I, D values?I guess this is a project to use Ziegler-Nichols method to calculate the p,ı,d values? I would be appreicated if you could contact with motor manufacterer and get the parameters of motor from them? answers are really appreciated
You might want to tune the PID parameter with trial and error method instead of by calculation. I don't think the manufacturer of the motor has those parameters either as they differ from one motor to another motor.
