| Abstract: | This paper deals with the guaranteed cost robust control for a class of uncertain linear discrete-time switched systems by employing the average dwell time method and piecewise Lyapunov function technique.State feedback controller is derived in terms of linear matrix inequality(LMI)such that the resulting closed-loop system is globally exponentially stable and has a weighted guaranteed cost upper bound.A numerical example is also given. |
