Solvability and Optimal Controls of Semilinear Riemann-Liouville Fractional Differential Equations

الملخص EN

We consider the control systems governed by semilinear differential equations with Riemann-Liouville fractional derivatives in Banach spaces.

Firstly, by applying fixed point strategy, some suitable conditions are established to guarantee the existence and uniqueness of mild solutions for a broad class of fractional infinite dimensional control systems.

Then, by using generally mild conditions of cost functional, we extend the existence result of optimal controls to the Riemann-Liouville fractional control systems.

Finally, a concrete application is given to illustrate the effectiveness of our main results.
