Switching Periodic Event-Triggered H∞ Control for NCSs and Its Application to UAVs

Based on the switching periodic event-triggered scheme (ETS), the control problem is investigated for networked control systems (NCSs) and its application to unmanned aerial vehicles (UAVs). Inspired by the switched system framework, a new switching ETS is proposed to reduce data transmission among the components of the NCS. The feature of the switching ETS is that the triggered conditions are scheduled by switching signals. The switching controller is model-dependent such that the studied NCS is modelled as a switching system with two time-delay subsystems. Applying the switching system technique, the criteria under the designed control scheme are established for stability and the H-infinity performance analysis. Finally, an UAV system and a networked invert pendulum are utilized to show the availability of the proposed switching ETS.
