PID I value tuning issues
Hey y'all,
So we've been tuning an auto-alignment feature for aligning with the goal (using vision). We're successfully filtering the image, and calculating the image and distance. In tele-op, we're using the built-in LabVIEW PID loop (see attached image). When we are tuning the PID constants, though, the I constant seems to have no effect. Our robot gets close to the needed angle, but even an extremely large (10^4) value for I seems to not change the robot's motion at all. Advice? We're relatively new to using PID control.
