Abstract The design of the gain-scheduled H2/H filter for polytopic discrete-time systems is investigated. By introducing additional slack variables, a new mixed H2/H performance criterion is proposed, which provides a decoupling between the Lyapunov matrix and system matrices. Based on the new performance criterion, a sufficient condition for the existence of the gain-scheduled H2/H filter is derived. Furthermore, the filter design problem is converted into a convex optimization problem with linear matrix inequality (LMI) constraints. Simulation results show the effectiveness of the proposed approach.
