摘要：
In this paper, we establish the existence and uniqueness of solutions for a nonlinear fractional differential equation with nonlocal boundary conditions. We employ Schauder fixed point theorem to study the existence of a solution of the problem. We also use the Banach fixed point theorem to study the existence of a unique solution. Finally, we provide examples to illustrate our results. Thus, we study the null-controllability for the fractional differential equation with constraints on the control. The main tool used to solve the problem of existence and convergence is an observability inequality of Carleman type, which is "adapted" to the constraints. We then apply the obtained results to the sentinels theory of Lions.
