Open-Loop Driving Feed Forward

Open jasondaming opened this issue 2 years ago • 2 comments

Document how to use a Feed Forward (ex. to offset turning static friction) to aid open-loop driving control. Doesn't need to use SysID either.

If you are using feedforward, that doesn't sound like open loop control?

Feed forward is forward it doesn't use and feedback devices (sensors). It only uses preconceived ideas about the system.

Open / Closed is determined if something is "closing" the loop be sending data back to the control algorithm so that it can make adjustments. There is nothing doing that here this is just a fancy version of adding 0.1 or whatever to the output.
