Abstract
A guaranteed state estimator produces a set of possible states based on output measurements and models of exogenous signals. In this paper, we consider the guaranteed state estimation problem for linear time-varying systems with a priori magnitude bounds on exogenous signals. We provide a recursive algorithm to propagate the set of possible states based on output measurements. We show that the centers of these sets provide optimal estimates in an l∞-induced norm sense. We then consider the utility of guaranteed state estimators for disturbance rejection with output feedback. In particular, we derive a separation structure for disturbance rejection in the special case of output feedback will full control.
