Synchronization of Van der Pol Oscillator By External Voltage of Double Frequency

Synchronization of the van der Pol oscillator is performed by an external sinusoidal voltage source of double frequency connected is series with the power supply and the oscillator. Modifying the oscillator effective supply voltage, this source modifies the coefficients of the van der Pol oscillator differential equation, and synchronizes the oscillator. The conditions and borders of synchronization are considered.
