Controllability results for fractional semilinear delay control systems (Q2053185)

In this paper, authors have presented the controllability relationship between the semilinear control system of fractional order \((1, 2]\) with delay and that of the semilinear control system without delay. They established the controllability results of the fractional semilinear system with delay by assuming that the fractional semilinear system without delay is approximate/exact controllable and by imposing some conditions on the range of the nonlinear term.
