In this paper, we present a "smart" high-peak power microwave tube, by implementing iterative learning control method-
ologies to control a repetitively-pulsed, high-power, backward wave oscillator. 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 experimentally verified.
I. Introduction
Present day high-peak power microwave (HPM) sources typically operate in the single shot regime because
of practical limitations imposed by the pulsed power systems used to drive them [1], [2]. There are however
commercial HPM systems that operate at modest repetition rates, two examples of which include a system
based on the reltron source [3] operating at 1 Hz, and a system based on a magnetron source [4] operating
at a 10 pulse per second burst mode. It is clear that a modest pulse repetition rate is attractive in pulsed
radar systems and electronic countermeasures (ECM).
The physics of the interaction between a relativistic electron beam and various slow wave structure con-
