Controllability of multi-term time-fractional differential systems

In this paper,an abstract multi-term time-fractional differential system is considered and the exact controllability results are investigated.In this theory,we tend to implement the basic tools of fractional calculus and measure of noncompactness to come up with a new set of sufficient conditions for the exact controllability by utilisation of Mönch fixed point theorem.Finally,an application is given to illustrate the obtained results.
