This paper will further present the results on the robust output regulation problem for discrete-time linear systems with input and communication delays. The motivation of this paper comes from two aspects. First, it is known that the solvability of the output regulation problem for linear systems is dictated by two matrix equations. While, for delay-free systems, these two matrix equations are same for both continuous-time systems and discretetime systems, they are different for continuous-time time-delay systems and discrete-time time-delay systems. Second, the stabilization methods for continuous-time time-delay systems and discrete-time time-delay systems are also somehow different. Thus, an independent treatment of the robust output regulation problem for discrete-time time-delay systems will be useful and necessary.展开更多

The existence of invasion wave solution is investigated by applying upper lower solutions method and Schauder＇s fixed point theorem. Further, with the help of Ikeharas＇ theorem, we establish the exponential decay asymptotic behavior of traveling wave solutions at the minus/plus infinity.展开更多
