PS – I’m thinking of wrapping the standard LabVIEW PID autotuning functions for use with the PID is this library. Just curious if there is interest in this?? ( I know PIDs are old technology with the state space functions in the library, but some old things are still pretty useful…)

I can’t say that we’ve ever used any kind of auto tuning. I’ve always been worried that our mechanisms cant handle the extremes.

Our students spent maybe an hour or two overall tuning our shooters speed control ( after they characterized the feedforward ). They did a good job but asked if there was another way… There always seems to be 5 more things demanding attention. So …. I wrapped some of the standard auto tune vi to make it easier to use. Right now there are 7 different standard tuning selections. Some are less aggressive. I added a sample test program in the sandbox project. This is still a work in progress. The tuning done calculation doesn’t handle noise very well yet. Otherwise it seems to work. I thought it might have value to teach the theory and not spend a lot of time trying different tuning or at least give a better starting point. Just some thoughts.
