  In this paper, the strong structural controllability of the network is
analyzed. Based on the unified definition of equitable partition for kinds of
scene, the upper bound of the strong structural controllable subspace in
different scenarios is given, and the strong structural observability is
analyzed by using the characteristics of the dual system. Finally, the
practical significance when the dimension of the strong structural controllable
subspace is less than the number of individuals is given, and an invariant
attribute of strong structural controllability analysis is proposed.
