In the presented work, we proposed a methodology of controlling the resonance
energy exchange in mechanical systems by creating appropriate electromagnetic fields around
the system’s structural subcomponents. It has been shown theoretically and confirmed experimentally
that properly guided magnetic fields can effectively change mechanical potentials in
such a way that the energy flow between the oscillators takes the desired direction. In particular,
a model of two weakly coupled pendulums subjected to an electromagnetic load using a
specific set of descriptive functions was considered. The developed control strategies are
based on the observation that, in the case of antiphase oscillation, the energy is moving from
the pendulum, which is in the repelling magnetic field, to the oscillator not subjected to magnetic
field. The advantage of the suggested control strategy is that the temporal rate of inputs
is dictated by the speed of beating, which is relatively slow compared to the carrying oscillations.
