An updated version of "Leader-following consensus for linear multi-agent systems via asynchronous sampled-data control," IEEE Transactions on Automatic Control, DOI:10.1109/TAC.2019.2948256

In this article, we update the reference [14] in two aspects. First, we note that in order for the control law (12) in [14] to be equivalent to the control law (3) in [14], we need to assume that the samplings for all subsystems must be synchronous, i.e., we need to assume that $T_i=T$ for all $i=1,\cdots ,N$. Second, we extend our results from periodic sampling to aperiodic sampling.
