Abstract：For time-varying linear systems,the distributed filtering is addressed for filtering networks with two-sided round-robin protocol(TSRRP)under random topology switching.Firstly,TSRRP is established for the filtering network,incorporating both the measurements for the plant and the interactive communications among the intelligent nodes within the filter network.That is to say only one filtering node occupies the communication resources at each sampling moment,which reduces the resource consumption of the filtering network and solves the problems caused by limited bandwidth and data conflicts.Secondly,a Markov chain is used to describe the topology switching of the filter network,and sufficient conditions for the exponentially mean square stability of the filtering error dynamics are given by constructing topology-dependent Lyapunov functions.The filter parameters are solved online by using differential linear matrix inequalities.Finally,the feasibility and applicability of the designed filtering is verified by numerical simulations and practical examples.
