When i increment/decrement it by 1, the motor seems to not run smoothly. You can tell its going too fast then too slow vice versa something like a resolution problem.<p>
This might be a case of the I part of your controller accumulating huge values because the rest of your controller takes too much time to get the motor to the desired speed. The large integral value then causes an overshoot. |
