Boundary Controllability of Riemann–Liouville Fractional Semilinear Evolution Systems

The main objective of this work is to steer a semilinear time-fractional diffusion control system involving Riemann–Liouville fractional derivative to a desired state in a part of the boundary of the evolution domain. For that, we use fixed point technique, semigroup theory and fractional calculus under some proposed assumptions in the linear part of the system and the nonlinear term. At the end, we provide some numerical simulations which lead to successful figures, in order to guarantee the efficiency of the proposed approach.
