The Kalman Filter (KF) is used to optimally estimate system states from the sequential noisy measurements of the outputs. On the other hand, real-time systems are often modeled with uncertainties and time-delays. Developing KF algorithms for such systems is an important problem to obtain optimal state estimates by utilizing the information on uncertainties and time-delays. First, designing of KF for nominal discrete-time systems is studied. Considering the covariance of the error in the estimation the KF algorithm is derived which is further tested on a numerical example. A designed KF is tested on a real-time problem i.e. Active Queue Management (AQM) problem. In Internet routers, Active Queue Management (AQM) is a technique that consists in dropping or Explicit Congestion Notification (ECN) marking packets before a router's queue is full
