I don't know if anything was "driving them" or if it was just a
coincidence of mathematics research... one of the most fascinating
courses I ever took in grad school was Nonlinear Control Systems,
based almost entirely on the works of Russian mathematicians, Lyapunov
is one that I remember who studied the stability of bang-bang servos.
