Delay-dependent robust l2 – l∞ filter design for uncertain Delta-operator time delay systems

This paper discusses the robust L2-Linfin filter design for delta-operator uncertain time delay systems. Applying the linear matrix inequality (LMI) technique, a sufficient condition of the existence of L2-Linfin filter is proposed and the design method of robust L2-Linfin filter for delta-operator uncertain time delay systems is derived. A numerical example shows the effectiveness of the method proposed.
