Hi friends, I need your help for the following problem:
I've a stepper motor connected to a big mass , so with some inertia.
Suppose that I know that the position is at angle A and I want to move to
angle B, which is the best way of modulating the angular velocity (or if
you prefer the number of steps / sec ) ?
At the moment I'm doing like this: I calculate B - A and every K / (B - A)
ms I do a step in the direction that decreases the distance.
I'm however not satisfied of the control. Can you suggest
something more efficient ? a PID ? do you have something to suggest to read
about motor control ?
thx
