Yet another option would be TBH.

Another option, at least in years past, was to feed the encoder values directly to a Jaguar, and the Jaguar would run the PID loop for you after you give it a set point. I am not sure what the equivalent motor controller of today is that can do that, however.

Talon SRX has built-in PIDF (Proportional/Integral/Derivative/Feedforward) if used in CAN mode.

In case you do decide to use the velocity Closed-loop in Talon SRX, checkout section 12.4 for a Java walk-through of Velocity-closed-loop.
