Quasi-periodic oscillation SUBHARMONIC RESONANCE IN A SYSTEM OF TWO DISSIPATIVE COUPLED VAN DER POL OSCILLATORS WITH EXTERNAL FORCE The problem of the excitation of two coupled oscillators is discussed in the case of the simple subharmonic resonance between the external force and eigen-frequencies of the oscillators. The corresponded phase equation is obtained. Read more about SUBHARMONIC RESONANCE IN A SYSTEM OF TWO DISSIPATIVE COUPLED VAN DER POL OSCILLATORS WITH EXTERNAL FORCE
