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.
