  This paper studies stochastic aperiodic stabilization of a networked control
system (NCS) consisting of a continuous-time plant and a discrete-time
controller. The plant and the controller are assumed to be connected by
communication channels with i.i.d. time-varying delays. The delays are
theoretically not required to be bounded even when the plant is unstable in the
deterministic sense. In our NCS, the sampling interval is supposed to be
determined directly by such communication delays. A necessary and sufficient
inequality condition is presented for designing a state-feedback controller
stabilizing the NCS at sampling points in a stochastic sense. The results are
also illustrated numerically.
