Hello,
I'm trying to track a particle using NI vision. That part works great. What I need now is to use a PID loop to control the voltage that controls the particles Y position location. I'm not getting it. Attached is one of the PID auto-tuning routines. What I need is to figure out how to change the voltage with respect to the particles Y coordinate. For example, if the position goes up, the voltage goes down. Any insight or hep would be greatly appreciated.
Thanks in advance
