| Generate stepper-motor speed profiles in real time
|
2005-01-03 |
| A new algorithm for stepper-motor acceleration allows speed profiles to be parameterised and calculated in real time. This algorithm can run on a low-end microcontroller using only simple fixed-point arithmetic operations and no data tables. It develops an accurate approximation for the timing of a linear ramp with constant acceleration and deceleration |
