Reverse or direct action in the PID controller?
15. March 2009
This video (15 minutes) describes how to select between the two basic settings reverse and direct action of a PID controller.
The video is based on the simulator pid_reverse_direct.exe which is in the zip-file pid_reverse_direct.zip. (You can run the simulator while watching the video.) Information about this simulator is available here.
The software needed to run the simulator is described here.
