Absolutely. At the moment the material is aimed at taking the viewer
from having no clue to being able to make a system that works well below
par -- there's a huge number of systems that don't need to be any better
than that.
Over the course of time I intend to expand the videos to cover real,
formal control system design. Videos take an incredible amount of work,
though -- I'm running about a week to produce a 15-20 minute video.

If you are heading for maximum bandwidth in an electr mech system though you will need a filter else it will shake itself to death! Many control systems work well below par of course.

Watch the video! I present both, and leave it as an exercise to the
reader to decide which is more appropriate.
Since the series is still at the level of seat-of-the-pants handwaving,
there really isn't a satisfactory explanation I can give as to WHEN you
need to use a bandlimited differentiator vs. when you can get away with
an unfiltered one. Once I present some theory I'll return to the PID
controller and give it a proper theoretical treatment, as well as showing
that one doesn't always automatically want _just_ a PID controller, or
even a controller that use all three elements.
