Re: blog; Motor Controller Options for 2015

I may not have the details quite right in this case but that's the general idea of PID for speed control.

For more on PID enter PID Controller in Wikipedia.
I know what PID is, but I'm wondering what specifically an onboard PID on the motor controller entails and how you could use it. My last post was pretty unclear, sorry.
For example, could you just send an error, output range, and gains to the motor controller and would it calculate the PID itself?
