Re: PID for velocity control

So we're not the only team whose Build Team can't quite understand "What part of DON'T cut the wires don't you understand?"

Re: PID for velocity control

Not to threadjack TOO much, but I am curious: do I need a really high resolution for D to work properly? I just have a resolution of degrees right now, because I am scaling the input before it hits the PID. It's just way too crazy to try to tune...I have a hack in place that zeroes the I term on my steering motor (guess what we're doing for a drivetrain... ) when we're inside a deadband...but I know that's not the right way to do it.

Does D fix my overshooting problems?

We're one of the teams that we need to tell our PROGRAMMING TEAM "What part of DON'T cut the PWM wires don't you understand?".
