Abstract-- In this paper, we present our progress toward
designing a "smart" high-peak power microwave (HPM) tube.
We use iterative learning-control (ILC) methodologies in order
to control a repetitively pulsed high-power backward-wave oscil-
lator (BWO). The learning-control algorithm is used to drive the
error between the actual output and its desired value to zero. The
desired output may be a given power level, a given frequency, or
a combination of both. The learning-control methodology is then
verified in simulation. This methodology is applicable to a wide
variety of HPM sources.

PRESENT-DAY high-peak power microwave (HPM)
sources typically operate in the single-shot regime
because of practical limitations imposed by the pulsed power
