Re: Tuning PID Constants Over a Range
I agree that a motion profile + feedforward to overcome static friction can solve this problem adequately for FRC purposes. However, the Talon SRX makes precise 1KHz velocity control stupidly easy to achieve; hiding the stiction nonlinearity behind a Talon and using plain old position PID is just as workable a solution these days. (But is still improved by using a motion profile of course)
