  Despite the significant advances in identifying the driver nodes and energy
requiring in network control, a framework that incorporates more complicated
dynamics remains challenging. Here, we consider the conformity behavior into
network control, showing that the control of undirected networked systems with
conformity will become easier as long as the number of external inputs beyond a
critical point. We find that this critical point is fundamentally determined by
the network connectivity. In particular, we investigate the nodal structural
characteristic in network control and propose optimal control strategy to
reduce the energy requiring in controlling networked systems with conformity
behavior. We examine those findings in various synthetic and real networks,
confirming that they are prevailing in describing the control energy of
networked systems. Our results advance the understanding of network control in
practical applications.
