Abstract:

The problem of H∞filtering for Delta operator based uncertain networked systems with limited communication is studied. Under the communication constraints, the networked control systems are analyzed by using a communication sequence,and the Delta operator formulated filtering error system with uncertainty is established. The performance analysis of network based H∞ filtering error system is proposed by constructing a suitable LyapunovKrasovskii functional via Delta operator which includes limited communication. Sufficient conditions of asymptotic stability for the filtering error system are derived in terms of linear matrix inequalities, and the design of H∞ filter is also obtained. A numerical example is given to show the effectiveness of the proposed method.
