  Model-Free Control (MFC), which is easy to implement both from software and
hardware viewpoints, permits the introduction of a high level control synthesis
for the Industrial Internet of Things (IIoT) and the Industry 4.0. The choice
of the User Diagram Protocol (UDP) as the Internet Protocol permits to neglect
the latency. In spite of most severe packet losses, convincing computer
simulations and laboratory experiments show that MFC exhibits a good Quality of
Service (QoS) and behaves better than a classic PI regulator.
