Stability of a ring of coupled van der Pol oscillators with non-uniformdistribution of the coupling parameter

Miguel Angel Barron


The stability of a ring of coupled van der Pol oscillators is studied in this work considering a non-uniform distribution of the coupling parameteralong the ring. The stability analysis is based on the transformation of the linearized equation of the ring into a canonical Hill equation. A stabilitycondition is derived considering the stability of the non-periodic term of the Hill equation. Stable and unstable dynamic behavior of the ring isstudied by means of numerical simulations.
