“…These conditions are the extension to the case of T-controllability of first-order dynamical control systems without delays [8]. Finally, it should be pointed out, that the obtained results could be extended in many directions: discrete-time [10,12,13,14]; second-order dynamical control [6,15]; linear fractional discrete-time [16,17,18]; switched systems [19,20,21,22,23,24,25,26,27,28,29]; infinite-dimensional systems [30] and fractional differential inclusions [31,32]. Moreover, controllability is strongly connected with the so-called minimum energy control problem [33,34,35,36,37,38,39,40,41].…”
