Just to clarify: It isn't PID vs Kalman filter. A Kalman filter is not
a control technique. It is a technique for obtaining the best
estimates possible in order to feed them as inputs to your control
law. You could have a Kalman filter feeding a PID controller.

As for the processor necessary, as Michael said, it depends on how
fast you need to do things but in most motion control applications
using Kalman filters, I would recommend using a processor with
hardware floating point.
