  This paper deals with controllability of dynamical networks. It is often
unfeasible or unnecessary to fully control large-scale networks, which
motivates the control of a prescribed subset of agents of the network. This
specific form of output control is known under the name target control. We
consider target control of a family of linear control systems associated with a
network, and provide both a necessary and a sufficient topological condition
under which the network is strongly targeted controllable. Furthermore, a
leader selection algorithm is presented to compute leader sets achieving target
control.
