This second of three volumes from the inaugural NODYCON, held at the University of Rome, in February of 2019, presents papers devoted to Nonlinear Dynamics and Control. The collection features both well-established streams of research as well as novel areas and emerging fields of investigation. Topics in Volume II include influence of nonlinearities on vibration control systems, passive, semi-active, active control of structures and systems, synchronization, robotics and human-machine interaction, network dynamics control (multi-agent systems, leader-follower dynamics, swarm dynamics, biological networks dynamics), and fractional-order control.
