“…The notion of CPS has been investigated so far in oscillators driven by external periodic force [15,16], chaotic oscillators with different natural frequencies and/or with parameter mismatches [11,17,18,19], arrays of coupled chaotic oscillators [14,20] and also in essentially different chaotic systems [21,22]. In addition CPS has also been demonstrated experimentally in various systems, such as electrical circuits [21,23,24,25], lasers [26,27], fluids [28], biological systems [29,30], climatology [31], etc. On the other hand CPS in nonlinear time-delay systems, which form an important class of dynamical systems, have not yet been identified and addressed.…”
