Delay-dependent robust l₂-l_∞ filter design for uncertain delta-operator time delay systems

摘要

This paper discusses the robust l ₂-l _∞ filter design for Delta-operator uncertain time delay systems. Applying the linear matrix inequality (LMI) technique, a sufficient condition of the existence of l ₂-l _∞ filter is proposed and the design method of robust l ₂-l _∞ filter for Delta-operator uncertain time delay systems is derived. A numerical example shows the effectiveness of the method proposed.
