| Abstract: | D stability of uncertain discrete-time systems with time delay was studied. When the parameters were assumed to be time-varying within a certain interval matrices, the controller guaranteed that the closed -loop system was regular, causal and D stable. The explicit formula of desired controller was provided by using the solution to the linear matrix inequalities(LMI). The numerical simulation result was provided to demonstrate the effectiveness of the presented method. |
