Indeed! Though I don't use the material on any regular basis (*), I
had four semesters on non-linear control theory in grad school. Great
fun, the real world!

(*) Though I recently was involved in a laser beam "wobulator"... a
mirror driven by a power amplifier... great fun tuning it up for
stability ;-)

Hey, the local paper here (Corvallis Oregon) led me to believe that
the "wobulator" was a local HP invention to double the resolution
of their HDTV projection systems. Don't tell me that such a neat
name actually got applied to more than one system!
