Popis: Autoresonant excitation and control of multiphase waves of the sine-Gordon equation is discussed. The autoresonance (a persistent nonlinear phase-locking) is achieved by applying chirped frequency wave-like perturbations and passage through resonances with inactive (dormant) degrees of freedom in the system. Successful phase locking requires the amplitude of the driving perturbation to exceed a threshold that scales as 3/4 power of the driving frequency chirp rate. The spectral theory of the inverse scattering transform method is used for diagnostics and analysis of the excited solutions.
