內容介紹:This talk investigates the mean square consensus problem for continuous-time  multi-agent systems with randomly switching topologies and noises. The switching  is governed by a time-homogeneous Markov process, each topology corresponds to a  state of the process. Meanwhile, the communication noises are also considered  for practical application. We introduce a time-varying gain which can reduce the  effect of communication noises. It is shown that the effect of Markovian  switching topologies mainly depend on the union of topologies associated with  the positive recurrent states of Markov process. Then necessary and sufficient  conditions can be obtained under a control protocol with time-varying gain.  Moreover, we extend our result to the cases that the elements of transition  rates matrix are partly unknown and the topological structure is semi-Markovian  switching. Finally, we give an example to illustrate the validity of our  results.
