Different modes of three coupled generators capable of demonstrating quasiperiodic oscillations

The dynamics of three coupled generators capable of demonstrating autonomous quasiperiodic oscillations is considered. The complex structure of Lyapunov charts of the system revealing invariant tori of different (high) dimensions, quasiperiodic bifurcations, Arnold resonance web, and other features is discussed. There was revealed the possibility of four-frequency tori in case of individual subsystems that exhibit the limit cycle mode.
