AB  - Decentralized    periodic    event-triggered    control(DPETC) strategies are an attractive solution for wireless cyber-physical  systems  where  resources  such  as  network  bandwidthand  sensor  power  are  scarce.  This  is  because  these  strategieshave  the  advantage  of  preventing  unnecessary  data  transmis-sions and therefore reduce bandwidth and energy requirements,however   the   sensor   sampling   regime   remains   synchronous.Typically  the  action  of  sampling  leads  almost  immediately  toa  transmission  on  an  event  being  detected.  If  the  sampling  issynchronous,  multiple  transmission  requests  may  be  raised  atthe  same  time  which  further  leads  to  bursty  traffic  patterns.Bursty   traffic   patterns   are   critical   to   the   DPETC   systemsperformance as the probability of collisions and the amount ofrequested bandwidth resources become high ultimately causingdelays.  In  this  paper,  we  propose  an  asynchronous  samplingscheme for DPETC. The scheme ensures that at each samplingtime, no more than one transmission request can be generatedwhich  prevents  the  occurrence  of  network  traffic  collision.At  the  same  time,  for  the  DPETC  system  with  asynchronoussampling  a  pre-designed  global  exponential  stability  andL2-gain  performance  can  still  be  guaranteed.  We  illustrate  theeffectiveness  of  the  approach  through  a  numerical  example.
