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!
I first heard of its use in an article of the early 1970's describing the
BBC Radiophonic Workshop unit's effects box of the late 1960's and early
1970's for distort actors' voices for Dalek characters in the series Dr Who!
