Re: PID control: need D values > 10000??

BDC-Comm is the TI tool for communicating over CAN bus directly to a Jaguar motor controller. No cRIO or Driver Station involved, which lets us try values quickly and without worrying about possible software bugs (at least outside the Jaguar).

We have a controls expert who was stymied at getting good PID control working due to the ineffective D term. I don't think it's our tuning procedure; it's either a bug in the Jaguar's firmware (which seems unlikely) or a problem in our understanding of the use of PID on the Jaguar (more likely).
