This paper studies a distributed discrete-time coordinated tracking problem where a team of vehicles communicating with their local neighbors at discrete-time instants tracks a time-varying reference state available to only a subset of the team members. We propose a PD-like discrete-time consensus algorithm to address the problem under a fixed communication graph. We then study the condition on...

This article is concerned with the local stabilization problem for discrete-time systems both distributed state delay and fast-varying input under actuator saturations. By introducing some terms concerning distributedly delayed current state, a novel polytopic model first proposed to characterize saturation nonlinearity. Then, by incorporating piecewise Lyapunov functional summation inequalitie...
