H ∞ stabilisation of networked control systems with time delays and packet losses.

This paper addresses the H-infinity state feedback stabilisation problem for networked control systems (NCSs) in the presence of time delays and packet losses. By introducing the concept of an effective sensor packet, the NCS is transformed into a new discrete-time switched model, where the parameters have a clear physical meaning and can be easily determined. In this framework, we derive the stability conditions of the closed-loop system in the H-infinity sense, and also provide the corresponding H-infinity stabilising controller design method. Finally, we give simulation and experimental results to demonstrate the effectiveness of the proposed approaches.
