三、摘要:
This talk discusses theH∞ performance of discrete-time networked systems subject to network-induced delays and malicious packet dropouts. First, the introduction of a data packet processor enables us to calculate both network-induced delays and the number of consecutive malicious packet dropouts explicitly. Second, a novel Lyapunov functional is constructed whose forward difference along with the trajectory of the closed-loop system is estimated as aquartic polynomial. A class of necessary and sufficient conditions on such an inequality are established by using Finsler lemma. By employing the Lyapunov method, a bounded real condition is formulated.
