Summary:This paper deals with the problem of the robust H∞ filtering for a class of Lurie singular systems with state time-delays, parameter uncertainties and unknown statistics characteristics but with limited power disturbance, aiming to design a robustly stable filter such that the uncertain Lurie time-delay singular systems are not only regular, impulse free and stable, but also have a prescribed level of H∞ performance for the filtering error dynamics for all admissible uncertainties. A sufficient condition for the existence of such a filter is proposed in terms of linear matrix inequalities （LMIs）. When a solution to this set of LMIs exists, the parametric matrices of a desired filter can be easily obtained using LMI toolbox.
