| | Feed Forward Loop (Site not responding. Last check: 2007-10-17) |
 | | One thing I do know (from brutal experience) is that feed forward his far more difficult to stabilize than feedback, so it would seem stupid to do a stepper with feed forward when a servo with feedback would give you better results more simply! |
 | | If velocity is changing, velocity feed forward term injects a term that is linearly related to the velocity (this is typically very useful when drive is operated in velocity mode OR when load is subject to a friction term that varies linearly with velocity). |
 | | Your feed forward question needs to be more specific, there are many feed forward components, Position, Velocity, Acceleration, and Friction. |
