At work, I am one of three designated

“servo guys,” and the only

one who implements control

loops in software. As a result, I often

have occasion to design digital

control loops for various projects.

I have found that while there

certainly are control problems

that require all the expertise I can

bring to bear, a great number of

control problems can be solved

with simple controllers, without

resorting to any control theory
