We extend the<br /> familiar LQG separation principle to this problem that allows us to solve this problem using a standard<br /> LQR state-feedback design, along with an optimal algorithm for propagating and using the information<br /> across the unreliable link. We present one such optimal algorithm, which consists of a Kalman Filter at<br /> the sensor side of the link, and a switched linear filter at the controller side. Our design does not assume<br /> any statistical model of the packet drop events, and is thus optimal for an arbitrary packet drop pattern.<br /> Further, the solution is appealing from a practical point of view because it can be implemented as a<br /> small modification of an existing LQG control design.<br /> | flags = <br /> | tag = gshm04-scl<br /> | id = 2004o<br /> }}</div>
