Re: PID Loop
PID is not a LabVIEW thing. It is a robust control algorithm that uses several mathematical terms based on proportional response, longer-term error accumulation, and how the current error compares to previous values.
LV does have an example called General PID Simulator that may be helpful to experiment with. It has a parameterized plant that allows you to model real-world elements and practice tuning them. But the model portion is pretty academic and not that approachable. Still, it allows you to experiment with typical tuning issues and identify the symptoms in the chart.
