Finite-time synchronisation of duffing-type oscillator networks by the figure analysis way

The finite-time synchronisation for a kind of coupled nonidentical drive-response Duffing-type oscillator networks is studied. Without adopting the finite-time stability theorems, by adopting the differential inequality skills and the figure analysis approach, two novel criteria to guarantee finite time synchronisation for the drive-response networks are attained. Our novel differential inequality skills and figure analysis way enrich and develop the theoretical treasure house of the finite-time synchronisation of dynamical networks.
