A robust L2 - L∞ filter design for uncertain networked control systems

In this paper, the problem of designing a robust L₂ - L_infin filter for networked control systems is investigated. A model is considered that take into account the network-induced delay and data dropout. Aim at the systems´ uncertainty, the uncertainty correlated with the states of plant is joined. Through the approach of Lyapunov-Krasovskii, the performance of L₂ - L_infin is transformed to a set of linear matrix inequalities that will be solved by a series of congruence transform. A numerical example is given to show the effectiveness of the method.
