PID Tuning

We're trying to get our robot to drive a predefined distance in Autonomous using the Talons SRX built-in PID. We tried numerous values for p, i, and d. The best we have been able to get to results in the motor stopping at about 10% past the input value. If we Set the Talon to 10000 ticks, it stops at 11000.

Unfortunately, I won't be able to look at the code for a couple of hours so I can't tell you what specific values we have.

Any suggestions on how to minimize the overshoot?

Lower the P value and/or lower the I value and/or raise the D value.

Re: PID Tuning

Do you have the Talons set for brake mode, or coast mode?
