主题:   Remote State Estimation: from Packet Dropping to Sensor Scheduling

Abstract: Inthistalk,we present some recent works in remote state estimation of a linear Gaussiansystem. In particular, our focus is on two aspects of remote estimation: packetdropping andsensorscheduling.  We start bygiving an overview of some existing results on estimation over a packet-droppingnetwork. This is followed by a discussion onsensorschedulingand an introductionof both offline and onlinesensorschedules, the latter of which is alsoknown as event-basedsensorschedules. We show thatthe offline schedules and some well-designed event-based schedules preserve theGaussianity of the system. Whenschedulingthesensortransmission over a packet-droppingnetwork, we show that it is not possible to design any event-based schedules,except the offline ones, which can preserve the Gaussianity of the system.
