In-phase synchronization in complex oscillator networks by adaptive delayed feedback control

V Novičenko, I Ratas - Physical Review E, 2018 - APS
In-phase synchronization is a special case of synchronous behavior when coupled
oscillators have the same phases for any time moments. Such behavior appears naturally for …
