PID Position & Velocity Control?
 

Our team has been able to use a PID loop along with an encoder to control the angular position of our shooting arm. However, we were wondering if it was possible to control how fast the arm reaches the target position. Could we tell it to slowly return to the ground over the course of a half of a second, then quickly snap upwards to fire the ball in just a tenth of a second? Essentially, we'd be telling the arm a target position and a target velocity. Could someone help us find a method to do this in Labview?

What you're asking is fairly complicated.

When you are moving the arm back down, why not just used a fixed motor output setting rather than a PID loop?

You might try slowly changing the target position when you want the arm to move slowly.
