摘要

This work focuses on the problem of full- and reduced-order l2-l∞ filter design for discrete-time Takagi-Sugeno (T-S) fuzzy stochastic systems.Firstly,we propose a basis-dependent condition for the existence of desirable l2-l∞ filters.Then by the convex linearization technique,we transform the derived condition into some strict linear matrix inequality (LMI) constraints.At the same time,both full- and reduced-order filters can be designed by solving those LMIs.What’s more,based on the projection lemma,we also provided a novel analysis method for the reduced-order l2-l∞ filter design.Finally,the feasibility of the proposed full- and reduced-order l2-l∞ filter design methods is verified by a numerical example.
