This is really easy to add into your calculations for the constant acceleration portion with
If you have a large velocity, you can't accelerate as fast.
This would let you achieve the most aggressive and fastest profile possible for when speed really matters. |
If you can experimentally (or analytically) determine the maximum speed
vmax and the maximum acceleration
amax, you could try using a linear relation:
acceleration = amax*(1-speed/vmax)
... and that would be easy to numerically integrate in a spreadsheet.
When speed=
vmax the acceleration is zero, and when speed=0 the acceleration is
amax.
