In dynamical systems, a Van der Pol oscillator is a non-conservative oscillator with non-linear damping.

Where x is a degree of freedom ( e . g . a vector of rigid body motions ), \ omega is the oscillation frequency, M is the structural mass and inertia A ( \ omega ) is the added mass ( frequency dependent ), B ( \ omega ) is the linear damping ( frequency dependent ), C is the restoring force coefficient ( similar to stiffness matrix in a structural dynamic function ) and F ( \ omega ) is the harmonic excitation force proportional to x and the wave height \ zeta _ a.
