  In this paper, a novel delay-independent control structure for a networked
control system (NCS) is proposed, where packet-based control strategies with
predictor-based and dual-rate control techniques are integrated. The control
solution is able to cope with some networked communication problems such as
time-varying delays, packet dropouts and packet disorder. In addition, the
proposed approach enables to reduce network load, and usage of connected
devices, while maintaining a satisfactory control performance. As a
delayindependent control solution, no network-induced delay measurement is
needed for controller implementation. In addition, the control scheme is
applicable to open-loop unstable plants. Control system stability is ensured in
terms of linear matrix inequalities (LMIs). Simulation results show the main
benefits of the control approach, which are experimentally validated by means
of a Cartesian-robot-based test-bed platform.
