摘要：
This paper reviews the mixed H-2/H-infinity filtering problem for linear time-invariant discrete-time systems with polytopic uncertainty. By introducing some additional free variables, a parameter dependent Lyapunov stability condition other than the quadratic stability condition is obtained in a polytopic domain, and then a much less conservative filter design approach is presented via solving some LMIs formulated with correspondence to polytopic vertices.
