Re: Pitching Machine Control - PID Needed?
In 2006, we used a relatively light shooting wheel (two skyway wheels). We designed it so that our "normal" shooting speed was 80% of full speed. When we ran it open loop at 80%, it would take about 1.5 seconds to get back to speed after shooting a ball. With PID control, it took 0.7 seconds. A shooting wheel with more inertia would have made both of these better.

I would recommend starting with open loop control, and if the students aren't happy with the result, then you can start teaching PID.
