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.

Bio: Ling Shi received the B.S. degree in electrical andelectronic engineering from Hong Kong University of Science and Technology,Kowloon, Hong Kong, in 2002 and the Ph.D. degree in Control and DynamicalSystems from California Institute of Technology, Pasadena, CA, USA, in 2008.
