Estymacja stanu w układach liniowych przy skwantowanych pomiarach wyjść
(Wydawnictwa AGH, 2011) Bania, Piotr
Paper describes state estimator for linear systems with quantized measurement. When quantization interval tends to zero estimator became Kalman-Bucy filter. If measurement noise intensity is low relative to quantization interval, then estimation error could be several times smaller than estimation error of Kalman-Bucy filter. Considerations are illustrated with examples.

Output collocation method for continuous state estimation from discrete output measurements in linear dynamical systems
(Wydawnictwa AGH, 2008) Baranowski, Jerzy
The goal of this paper is to introduce a new method for dynamical system output approximation - output collocations. The need for such approximation arises when the measurements are discrete in time and we want to estimate the continuous state of the system. Such approximation can be used along with a continuous asymptotic observer as part of a solution for continuous state estimation from discrete output measurements (CSEDOM) problem. The presented method is designed specially for this task and, besides output measurements, it uses the CSEDOM information from earlier iterations. This method is also presented along with classical interpolation approach which was considered in the author's previous works.
