摘要：
This study deals with the problem of H-infinity output-feedback control for switched linear discrete-time systems with time-varying delay. A delay-dependent stability criterion for a given H-infinity performance is derived by employing finite sum equality based on quadratic terms, a new method of estimating the upper bound on the finite sum. Both static and dynamic H-infinity output-feedback controllers are designed based on a performance analysis. Moreover, a modified cone complementary linearisation algorithm is exploited to solve the nonconvex feasibility problem. Numerical examples are given to illustrate the theoretical results.
