报告内容摘要：

In this talk, a novel result is presented to guarantee uniform global asymptotic stability of a class of switched linear time-invariant discrete-time systems. Then, it is applied to leaderless and leader-following consensus problems of discrete-time multi-agent systems under jointly connected switching network topology. Different from the continuous-time multi-agent systems under switching networks, where the magnitude of the dwell time of the switching signal is irrelevant, in the discrete-time case, this value is critical for consensus reaching. A tighter lower bound of the dwell time is given compared to those in the literature. Moreover, the controllability condition on the system matrix is relaxed to the stabilizability condition. Numerical examples are provided to verify the theoretical results.
