Re: LabVIEW PID for angles

LabVIEW PID functions don't care whether the variables represent angles, speeds, temperatures, etc. They're just numbers.

It seems that the specific application you have in mind assumes motor control of a mechanism capable of continuous rotation and negligible time for changing direction. That's not the only kind of mechanism one might want to control based on angle. Since each application is going to have its own requirements, a built-in function would have to have a lot of options, and it still might not accommodate some needs.

I think you're trying to ask whether there is a built-in function that combines PID with the specific way you want angular errors to be computed. You're the one who knows how you want it to work, so I don't think it's any great burden to have you implement that part of it yourself.
